Ambar Kulkarni, PhD

Dexter is, without a question, one of the top 3 graduate students I have mentored at UC Davis and Stanford. He has an uncanny ability to (1) acquire the necessary domain knowledge by reading the relevant literature, (2) identify achievable short and long term goals, (3) develop data science tools to address them, and (4) implement the optimized solution as a robust software package. This ability has been exemplified during his graduate work, where he developed open-source Python packages for computational chemistry and automated experimentation applications. Dexter is a team-player, a good (and organized) mentor, and is passionate about his work. He will be an asset to any team that he decides to join.
