Dominic Diaz

PhD Student AT Cornell

Dominic Diaz is currently a fourth year PhD student at Cornell University. He started studying applied mathematics and physics at UCLA in the Fall of 2015. Over the course of his undergraduate education he joined the learning assistant program, completed a Research Experience for Undergraduates, and did research with various professors. After developing passions for teaching, machine learning, and research, he decided to pursue a PhD in applied mathematics at Cornell University. Dominic currently does research on how machine learning methods can extract mathematical models from swarming behavior (like in bugs and birds). He also fondly remembers avoiding Bruinwalk, late nights in Powell, and Rende.

Elijah Gross-Sable

Houlihan Lokey

Elijah Gross-Sable graduated UCLA in 2021 with a BS in Applied Mathematics and a Specialization in Computing. Elijah currently works in the Financial Restructuring Group at Houlihan Lokey, an independent advisory investment bank headquartered in LA. In this role, Elijah prepares financial models and other materials to help in structuring and negotiating transactions on behalf of companies and their creditors.

Teresa Rexin

PhD Student at UCSD

Teresa Rexin was raised in Sacramento County and is finishing her Master’s in Statistics at UCSD this June. She graduated from UCLA in Fall 2020 with a B.S. in Applied Mathematics and minor in Statistics. While at UCLA, Teresa was an Undergraduate Researcher investigating real-world applications of networks, a peer tutor for the UCLA Statistics Club, a Technical Advisor and Data Blog Editor for DataRes, and a 2021 Chancellor’s Service Award Recipient. Teresa is interested in responsible AI/data ethics, and she has several years of experience as a Data Science Intern at Intel and Microsoft–she starts working full-time as a Data Scientist at Microsoft this fall. At UCSD, Teresa is a Teaching Assistant for the senior Data Science Capstone and introductory Principles of Data Science courses, a Graduate Researcher working on time series analysis and graphs, and a Mentorship Co-Coordinator for the Math Graduate Student Council and UCSD’s chapter of Association for Women in Mathematics. In her free time, she enjoys volunteering, exploring the beaches and hiking trails in San Diego, baking and cooking new recipes, gardening, and reading.

Juan Carbajal

Software Engineer

Juan grew up in Los Angeles and Mathematics was a passion of mine from an early age. Juan arrived at UCLA in the Fall of 2016 and declared a Financial Actuarial Mathematics major. Over my time at UCLA, as he learned more about what he liked, Juan ended up pursuing Applied Mathematics instead. It was this major that introduced me to the PIC courses offered by the department, and that’s where he discovered my passion for coding. He landed my first software developer role for a nonprofit organization near the end of my fourth year, where he helped design and implement an online code editor website for students in grade school to use. After half a year working there he then spent a couple months at an internship working on an Android/iOS puzzle game. This short work led to me being offered a Co-Founder position as a Software Engineer for this newfound startup company called Trivial. Juan took the offer and spent about 15 months building up this new integration platform while our CEO sought funding. Now, with a bit of experience under my belt, he just recently began searching for a new role in Software Engineering.

Daniel Gutierrez

AMULET Analytics

Daniel D. Gutierrez is a practicing data scientist who’s been working with data long before the field came into vogue. As a technology journalist, he enjoys keeping a pulse on this fast-paced industry. Daniel is also an educator having taught data science class at UCLA Extension for a number of years. He has authored four computer industry books on database and data science technology, including his most recent title, “Machine Learning and Data Science: An Introduction to Statistical Learning Methods with R.” Daniel holds a BS in Mathematics and Computer Science from UCLA.

Vikas Thakur


Vikas (Vik) Thakur is a Vice President in Partnerships and Alliances at Genpact – a global professional services firm that drives digital-led innovation and digitally embedded intelligent operations for global clients (really fancy words for applying technology to improve client operations).  Vik’s first summer job while he was an undergraduate Math major at UCLA was as an Orange Juice Taster for a local juice company.  Applying analytic techniques he learned at UCLA, Vik improved the juice blending process to create a more consistent quality product.  This awakened a passion in him to help organizations “work smarter, not harder”.  Vik pursued his passion by becoming a Transformation Consultant to help organizations improve their performance.  He worked for major consulting firms, such as Deloitte Consulting and Genpact, to help clients rethink their approach to operations.  He also worked for major companies like Exxon, Bank of America, and Countrywide Financial to help lead the change from within.  Vik holds a BS in Mathematics / Applied Science and an MBA from UCLA.
