Meghna Pancholi is a second-year PhD student advised by Associate Professor Simha Sethumadhavan. She is interested in cloud computing, systems security, and microservices. Before Columbia, Meghna was an undergraduate researcher at Cornell University where she worked on improving the performance of microservices applications with machine learning techniques.

Meghna graduated from Cornell University in 2020 with a BS in Computer Science.


Clayton Sanford
Clayton Sanford is a third-year PhD student working with Professors Rocco Servedio and Daniel Hsu on machine learning theory. The motivating goal of his research is to understand mathematically why deep learning performs so well in practice. Clayton’s work on the approximation capabilities of neural networks has been published at the COLT 2021 conference. He is a member of the CS Theory Group.

Clayton received an ScB in Applied Math and Computer Science with honors from Brown University in 2018.


Sky Wang
Sky Wang is an incoming first-year PhD student set to work with Assistant Professors Zhou Yu and Smaranda Muresan. His work focuses on natural language processing and he is interested in leveraging computational methods to understand social aspects of language and to use such insights in creating more effective and more equitable language technologies. He is particularly interested in the areas of situated dialogue systems, computational social science, and cultural analytics.

Wang graduated in 2020 from the University of Michigan with a B.S.E in Computer Science. He is a 2021 recipient of the University of Michigan’s EECS Undergraduate Outstanding Research Award and also received an honorable mention for the Computing Research Association Outstanding Undergraduate Research Award in 2021. He received a Best Poster award from the University of Michigan AI Symposium in 2018 and was recognized as a finalist in the NASA Goddard Space Flight Center Intern Research Fair in 2018.


Joseph Zuckerman
Joseph Zuckerman is a second-year PhD student in computer science at Columbia University, where he works in the System-Level Design group, advised by Professor Luca Carloni. His research interests include architectures, runtime management, and agile design methodologies for many-accelerator systems-on-chip.

Zuckerman contributes as one of the main developers to ESP, an open-source research platform for heterogeneous system-on-chip design. In 2019, he completed his S.B in electrical engineering at Harvard University, during which he completed internships at NVIDIA and the NASA Jet Propulsion Lab.


SEAS Fellowships

Columbia School of Engineering and Applied Sciences established the Presidential and SEAS fellowships to recruit outstanding students from around the world to pursue graduate studies at the school.

Blavatnik Fellow

Sebastian Salazar
Sebastian Salazar’s research interests include Machine Learning and Ethical AI. At Columbia, his work will be focused on counterfactual predictions and actionability of Machine Learning models. He is a first-year PhD student who will be working under the guidance of Ansaf Salleb-Aouissi.

Sebastian graduated magna cum laude from Columbia University in 2021 with a B.S. in Applied Physics.


Dean’s Fellows

Huy Ha
Huy Ha is an incoming first-year PhD student interested in computer vision, natural language processing, and robot learning. His research studies how embodied intelligence could combine information from different modalities (vision, language, interaction) to understand its environment, solve tasks, and assist people. He is advised by Assistant Professor Shuran Song and is a member of the Columbia Artificial Intelligence and Robotics (CAIR) lab.

Ha graduated in 2021with a BS in Computer Science from Columbia University. He was a Dean’s Fellow and received the Theodore Bashkow Award.
