I am a 4th-year PhD Candidate in Operations Research at Georgia Tech ISyE, advised by Dr. Juba Ziani. My research interests lie at the intersection of OR-CS-Econ. In particular, I work on decision-making problems with humans in the loop, with specific emphasis on strategic behavior, privacy and fairness. [research statement]* 

Some key aspects of my current work involve: i) design of mechanisms/markets for responsibly collecting and transacting data; ii) studying the benefits and harms of AI-assisted decision making; and iii) understanding long-term fairness in resource allocation in dynamical systems and designing interventions for the same. I am also actively interested in mechanism design for the LLM-disrupted future! For example, see these two papers which I love [1][2].

Support: I am grateful to have been supported in the past by the Stewart Fellowship, the Jerry & Harriett Thuesen PhD Fellowship and the ARC-ACO Fellowship! 

Note: My first name is derived from two Bangla words 'deep/দীপ' (source of light) and 'ansh/অংশ' (portion/fragment) which put together, mean 'fragment of light'. However, given that it is significantly hard to say (and I feel physical pain when it is butchered), for all practical purposes, I prefer to be called Sen.
