Meet a Computer Scientist

Sunday, February 24th, 2008

It’s National Engineering Week in Ontario to celebrate here is another profie.

Rebecca Lantz is a Computer Scientist who is a team lead in the wireless group at Alcatel-Lucent in Ottawa. We talked about her path to working in a technical job and started back in the high school years. Like most young people in high school she had no idea what to do after she graduated. Rebecca liked English, Math and Accounting and seemed to focus mostly on business courses. She never took any drama or arts courses. She liked school and when she graduated she followed in her parents’ path and attended Queens University. She took applied science and picked physics as her major. To her dismay she did not like physics and quit university. It turns out that this was the most empowering thing in her life.

“I was in charge of my life. I found an apartment, got a job at a drug store and supported myself. This empowered me to do whatever I wanted. I helped with the bookkeeping, ran the post office, helped at the pharmacy, cash, photo lab and computer system.”

She was there for 8 months and although it was a lot of fun initially, it lost it’s appeal once she learnt everything. In search for a bigger challenge she decided to go back to school. Since she helped out with the accounting and enjoyed it she decided to take business courses at college.

“I went to Sir Sanford Fleming College in Peterborough and took business administration. I was enrolled in the accelerated program which took two years. My highest marks were in accounting but the classes that I enjoyed the most were computer related, like information systems.”

Although Rebecca found the courses related to computers very interesting she almost quit the program because the business courses did not interest her. She had a discussion with the administrator of the program and expressed her interest in doing something more technical. She stuck it out and graduated from the business program at the top of her class. She was approached by one of her instructors to work on a research project programming in C++. He was a master C++ author. So her first programming job was after college.

“I worked on a research project for Trent and Peterborough paper converters. I worked on a statistical process controller (SPC) with an integrated expert system. An SPC has a sensor server hooked to an optomux. This optomux had sensors on it for temperature, speed, counter, measuring paper going through the machine etc. All this information went through the optmux and then the optomux went through the sensor server. The inputs were normalized into meaningful numbers. These normalized numbers are fed through a cable to another computer. I worked on the graphics in C++ on dos.”

She worked on this research project for 2 semesters and it was the most amazing work experience.

Prior to graduating from college, Rebecca applied to various universities. She eventually went into the Computer Science Program at McMaster University, as they transferred the most credits. Since she liked the technical courses I asked Rebecca why she chose computer science and not engineering.

“I did not have grade 13 chemistry therefore could not do first year engineering unless I took the chemistry courses. I was also more interested in programming than internal hardware at that time. The low level computer stuff.”

We talked about the transition from college to a technical program. There seemed to be advantages to working, supporting herself and attending college. However it had been a few years since she took any math courses.

“It was scary at this point as I had not done any serious math or science in three years. On the other hand I was a step ahead of everyone else as I learnt how to study and learn in that environment. How to form study groups, memorize the important stuff, how to sit down and read a text book and stay awake and process it.”

She had a reduced work load a lot of the time due to the transfer of credits from the college program. This gave her some breathing room.

Between second and third year Rebecca started a sixteen month internship at Nortel in Ottawa. This was possible due to her prior programming experience.

“I programmed in C++ for eight months and was somewhat of an expert in the group. C++ was new and most of the full time employees had not used it before. I was in for a shock as I had always worked in a small environment where there were two to five people on the project. At Nortel I was one of two hundred and had no idea of how the overall system worked. This was a hard adjustment.

It’s very distressing from going from a half cup of water to a drop in an ocean. I did not understand what the product did. People had a bunch of documents with pictures on it which I had to read. The good thing about the internship is that it’s for sixteen months’ therefore people were interested in investing time in training me.

They partitioned a piece of design work for me and I was interfacing with people in California and Ottawa. During that time I learnt a lot and became more interested in the hardware. One of the managers had taken his Masters at McMasters in Computer Engineering and got in touch with the professor there and suggested letting me take some Computer Engineering courses, low level with assembly programming.”

Rebecca continued to study computer science however all her electives were in computer engineering. She read a book in the summer that helped her catch up to the second year Computer Engineering courses. After completion of here third year she was back at Nortel, this time in the ATM port management group. This job was closer to the hardware and had to do the testing of the SONET SDH. This was done using a protocol analyzer. The second half of the summer was spent programming flash devices.

She continued to work part time, remotely, from McMaster. The summer after graduation she again worked at Nortel and was back in the same group as her internship doing C++ programming.

In the fall of that year she was at the University of Victoria, on an NSERC grant, working on her Masters in Computer Science. She was for only two months before she realized that she was burnt out from school.

“I was living two blocks from the ocean and living in one of the most beautiful cities in the world however she was spending most of her time indoors.”

She quit the program and traveled around for a while after which she moved to Ottawa to settle down and get married.

“I never had to write a resume and only did this once for the internship. The jobs that I had after were all through word of mouth. I went back to the OAM switch and worked here full time. I got married, bought a house and started a family.”

Rebecca is very fortunate to have used everything that she worked on in all her jobs that she has had.

“The initial product that I worked on at Nortel became the platform for the wireless program I am in now. I have had the advantage of always having to grow on top of everything that I learnt before. Nothing has been wasted and comes in handy all the time. I have used every thing that I learnt in school on the job.”

Rebecca has turned down management positions many times as the business side does not appeal to her.

“I don’t want to fill out schedule points and be responsible for peoples careers; this is not interesting to me. I want to be part of the technology, fix problems, participate in the architecture, and work on designs. I want to pull together the complicated pieces of the puzzle in designing new or fixing something that is broken.”

Shortly after moving into wireless and became team lead went to work part-time. She works hard for 4 days a week and the other three days are devoted to her family or herself. In her spare time Rebecca attends yoga classes and dance classes. She has done belly dance, tap dance and African dance.

Meet an Electrical Engineer

Friday, February 15th, 2008

ezA_Karen.JPG National Engineering Week is round the corner and as promised here is the first post in the “Women in Engineering” series.

Karen Chow is an Electrical Engineer who currently works as a Technical Marketing Engineer for Mentor Graphics in Portland, Oregon. I asked her if she always wanted to be an engineer or was it something that she discovered along the way.

We started our discussion with what she liked in high school.

“Back in high school I liked math, chemistry, physics as well as music. I excelled in these subjects. When it came time to deciding what to do after high school it was hard to know what I wanted. I liked math, chemistry and physics and did well in them. My councilors suggested that I go into engineering.”

She did not have anyone in her immediate family who was an engineer and heard about engineering through her councilors. She was good in music as well as the sciences. We talked about what programs she applied for in university.

“I applied to different programs, music, science and engineering, to keep my options open.”

She was accepted into these programs however chose to have a career that was somewhat practical.

“I made my decision by looking at it from a practical point of view. Music would always be a part of my life but it’s hard to make a good living. There are very few jobs in chemistry that make a good living. So I accepted engineering”

“The first two years of engineering, at the University of Calgary, are common engineering courses. I gravitated towards electrical engineering courses”

We talked about co-op jobs and internships. There was an internship program in the third year however she did not make it into the program and found a summer job instead. This job was for a programmer in relational databases which later proved to be valuable job experience.

“After graduating I was offered a job at Nortel, in Ottawa, in the Provisioning group, which is about entering information into the switch. There were 200 people working on this project and I had a narrow, specific task to do. There were code reviews and well defined processes to follow.”

Being a large company, Nortel had very well defined processes and code reviews. It was a great first job as there were a lot of people to lean on and learn from. She worked in this group for two years but found that she was not using a lot of what she learnt in her undergraduate program. She had taken only four programming courses but more hardware related courses. Wanting something more related to engineering, she took some master courses. This opened the door to an analog IC design job which dealt with Bode Plots, analog design and half the courses in undergrad applied to this job.

“This job was very different as there were a few people working on this project. I was one of three designers and there were only 6 people on this project. This meant that I had a lot more responsibility however there was a lot of coaching from the team lead and managers.”

Karen spent two years doing Analog IC design and then left Nortel to work for Mentor Graphics as an Applications Engineer. Her analog design experience combined with her excellent communication skills made her the ideal candidate for this job. In this department five out of six engineers were women leading her to believe that women preferred to have jobs that needed a combination of engineering and good communication skills.

“This job was somewhat generic as the amount of the commission, for all of Canada, was determined. I had to support ten tools and basically make things happen. My manager was in Toronto therefore only one on Canada supporting this particular tool. I made a lot of cold calls, seminars and workshops. I worked with account managers, talked with people in the office and tried different things.”

This job was not structured and she had to figure out what worked and how she could be effective. Although it was an applications engineer position it was somewhat sales oriented with a high emphasis on relationship building and problem solving. The only guidelines that Karen had were the quota and how to do the best with her personality and skills to find the best solution.

After a few years in this position Karen moved to Portland to join the Marketing team as a Technical Marketing Engineer .

“This role is one more step away from engineering. It combines the understanding of IC design and parasitic extraction. I work with engineering, application engineering and give customer feedback to engineering. I give training, workshops, seminars and write articles for magazines.”

Karen has written various technical papers and articles which can be found at EE Asia, Mentor and RF Design. Her role within the team is defined by each person’s strengths and skills.

We talked about what she does asides from work. Karen has continued her interest and passion for music and currently plays bass in a 80s cover band. She is participates in various sports. She likes karaoke and her latest hobby is quilting.

Karen finds engineering very interesting with new technologies. It encompasses a wide range and can be technical or people focused. So lots of opportunities and fun jobs.

Women in Engineering

Wednesday, February 13th, 2008

When I was in university there were about five women in a class of sixty Electrical Engineering students. My first job out of university resulted in a similar number. Now years later the statistics are not much better for women in technical programs.

The University of Texas at Austin has some interesting statistics. In the Fall of 2007, only 12.6% of undergraduate students enrolled in Electrical Engineering were women. The statistics for other programs are somewhat similar with Biomedical Engineering being as high as 37.2%.

In 1999 the Society of Women Engineers posted some results that are based on employed engineers. The ratios of Electrical are somewhat similar, there were some improvements in Civil Engineering.

If women are consumers of engineering products and services then shouldn’t they be involved in this process? So why are the percentages not higher? Is it that young women are dropping math in high school? Do they not have enough female role models?

The Extraordinary Women Engineers Project addresses some of these.

To celebrate National Engineering Week I will profile some women engineers on this Blog. In the interim you can check out some cool engineers.

Winterlude 2008

Sunday, February 10th, 2008

I went to Winterlude, in Ottawa, last weekend. It was the first time that I had attended Winterlude on opening day. This gave me the chance to see the different artists hard at work creating their sculptures. They took big blocks of ice and used various tools to carve out the different shapes. Getting the blocks of ice to stay together is quite the art as it involves scraping the ice block until it’s even, heating a piece of aluminum and putting this on the block to melt it a little. The other block is placed on top, thus becoming “glued” together.

The person in the photo is one of the ice carvers and has been coming to Ottawa from the U.S.A for the past three years. He teaches culinary arts and enjoys coming to Ottawa for Winterlude. His creation ……

National Engineering Week (NEW)

Monday, February 4th, 2008

Did you know that there was something called National Engineering Week(NEW)? Yup, you read correctly, a whole week dedicated to engineers and engineering. This is celebrated in a number of countries world wide. In Canada it is from Mar 1st – 9th, in the U.S.A. it’s from Feb. 17th-23rd and in Britain from March 7th-16th.

Being an engineer, I think it’s totally awesome that there is a whole week dedicated to engineering!!! Not a day but a whole week!!! Why is that? Stumped I decided to investigate this a little further.

What do engineers do? Engineering has been called the “stealth profession” because most people have no clue what engineers do and what engineering is about. That’s somewhat surprising since engineering has been around for a very long time. To try to understand this I thought that I would list the different types of engineering and what they all mean.

Here goes

  1. Acoustical Engineering – branch of engineering dealing with sound and vibration
  2. Aerospace Engineering – deals with spacecraft that leave the earths atmosphere
  3. Aeronautical Engineering – deals with aircraft that stay within the earths atmosphere
  4. Agricultural Engineering – apply engineering science and technology to agricultural production and processing, and to the management of natural resources
  5. Automotive Engineering – branch of vehicle engineering incorporating elements of mechanical, electrical, electronic, software and safety engineering as applied to the design, manufacture of automobiles, motorcycles, buses and trucks
  6. Bioengineering – application of engineering principles and design to challenges in human health and medicine.
  7. Biomedical Engineering – application of engineering principles and techniques to the medical field.
  8. Chemical Engineering – branch of engineering that deals with the application of physical science, math, to process of converting raw materials or chemicals into more useful or valuable forms.
  9. Civil Engineering – deals with the design, construction and maintenance of the physical and natural built environment, including works such as bridges, roads, canals, dams and buildings
  10. Computer Engineering – application of engineering principles to the design and development of hardware and software systems
  11. Electrical Engineering – application of electricity, electronics, electromagnetism, power, control systems , signal processing and telecommunications.
  12. Engineering Management – Engineering management involves the overall management of organizations with an orientation to manufacturing, construction, engineering, technology or production
  13. Engineering Sciences – integration of sciences with areas of traditional engineering such as research, design and analysis
  14. Environmental Engineering – is the application of science and engineering principles to improve the environment (air, water, and/or land resources), to provide healthy water, air, and land for human habitation and for other organisms, and to remediate polluted sites
  15. Genetic Engineering – Genetic engineering uses the techniques of molecular cloning and transformation.
  16. Geotechnical Engineering – the engineering behavior of earth materials
  17. Industrial Engineering – is a branch of engineering that concerns the development, improvement, implementation and evaluation of integrated systems of people, money, knowledge, information, equipment, energy, material and process
  18. Manufacturing Engineering – application of control engineering procedures in manufacturing processes and methods of production of industrial commodities and products
  19. Marine Engineering – are the members of a ship’s crew that operate and maintain the propulsion and other systems on board the vessel
  20. Materials Engineering – involving the properties of matter and its applications to various areas of science and engineering
  21. Mechanical Engineering – application of physics for analysis, design, manufacturing and maintenance of mechanical systems.
  22. Metallurgical Engineering – study of physical and chemical behavior of metallic elements, their intermetalllic compounds and their compounds, which are called alloys.
  23. Mining Engineering – other engineering disciplines as applied to extracting and processing minerals from a naturally occurring environment
  24. Nuclear Engineering – application of the breakdown of atomic nuclei and/or other sub-atomic physics, based on the principles of nuclear physics
  25. Ocean Engineering – concerned with the design, analysis and operation planning of systems that operate in an oceanic environment
  26. Petroleum Engineers – the exploration and production activities of petroleum as an upstream end of the energy sector
  27. Software Engineering – application of a systematic, disciplined, quantifiable approach to the development, operation, and maintenance of software

There you have it, 27 different types of engineering explained. I was quite surprised by this number and I am sure there are a lot more.

Now I understand why we need a whole week, as one day would not be enough to cover all the different types of engineering.
