Preferred Pronouns: He / Him / His

What Certificates or Degrees in Computer Science Do You Hold?

A bachelor of science. I also have a bachelor of science in applied mathematics, a master of arts in mathematics, and a doctorate in mathematics.

Why Did You Choose to Study Computer Science?

Initially, I enjoyed the problem-solving nature of programming. As my studies continued, I got very interested in how to apply math to solve real-world problems.

The first spot I encountered this was in a required linear algebra course for all computer science majors. The class had an option to complete a project in image processing, where I learned to write programs to automatically find and extract objects inside of images. After completing this project, I shifted my computer science focus to numerical computation and took more courses in applied mathematics.

Did You Specialize?

My focus was numerical computation with an emphasis on numerical linear algebra and computational differential equations. I focused on two different application areas: image processing, including deblurring, segmentation, compression, and building 3D simulations of solid materials, including skin and muscle tissue.

What Do You Do for a Career?

I left academics shortly after finishing my Ph.D. I now build data-driven products for companies. I'm currently CTO at Nami ML.

I've also worked in the data science field, most recently as VP of data at two different journalism companies. I built tools to increase engagement with digital news products and accelerate the transition of subscribers to the online news from the print paper.

I also worked at Timeline Labs, building algorithms to detect breaking news on social networks before it was reported by the news networks.

What Advice Would You Give Someone Considering a Computer Science Education?

Study what you love. Many courses in school do not translate directly to on-the-job skills, and that's okay. School, more than anything, is about learning how to learn.

This is especially true if you go on to get a master's or doctorate. If you do not love what you are studying, it can be hard to finish your degree. While some coursework might help you land that first job, after your first job, no one is going to ask to see what classes you took again.

If you have an interest in math or statistics, adding this coursework to your computer science studies can open a lot of doors, especially with the explosion of data science as a field.

What Degree Do You Recommend for People Interested In an Entry-Level Computer Science Career? And for People Looking to Advance Their Careers?

If you are looking to get a job as a developer at most tech companies, a bachelor's is all you need. Skip the Ph.D. unless you are looking for a job as a researcher. It is a long commitment, and a bachelor's or master's is more than sufficient to land an interesting job.

If you are looking for a job with more of a data focus, getting a master's degree and taking coursework related to data science and statistics can help with getting that first job.

If you only have a bachelor's degree and really want to work in data science, find a kaggle.com dataset that you are interested in. Kaggle runs data science competitions and provides data sets to work with. It is not so important to compete, but make a solution, present your work in a Jupyter notebook, and upload it to your personal Github account.

If you have no experience as a data scientist, this gives job recruiters something concrete to review, and it can often help land that first entry-level job as a data scientist, analyst, or machine learning engineer.

What Value Do International Programs Offer Students, In Your Opinion?

International programs can really help you land that first job (both in industry and academics) in a country or region where you do not have citizenship.

If you know you want to work in Asia or Europe, complete a program at a school in that region. Career fairs and academic conferences will introduce you to people hiring in those regions. Oftentimes, you can get a work visa. This will enable you to get that first job if you completed your degree in the country you want to work.

The Optional Practical Training Extension for STEM Students program in the United States is a great example open to computer science students who are not authorized to work in the U.S.
