About

I am a Ph. D student at the Indraprastha Institute of Information Technology (IIIT), Delhi and also an IBM Research Fellow. My academic advisors are Dr. Raghava Mutharaju (IIIT, Delhi) and Dr. Sumit Bhatia (Adobe, India).

My doctoral research focused on developing benchmarks for description logic reasoners, encompassing static, streaming, and neuro-symbolic reasoners. This work has given me extensive expertise in several knowledge graphs and semantic web-related technologies, such as Ontology (OWL 2) Modeling, Conventional Static Reasoning (Tableau and Rule-based reasoners), SPARQL Query Engines, Temporal and Stream Reasoning, and Neuro-Symbolic Reasoning (including KG Completion, Deep-Deductive, and Inductive Reasoning methods). I have also worked on projects exploring non-conventional learning-based methods for efficient reasoning over expressive ontology languages such as OWL 2. My research interests include Machine Learning and Reinforcement Learning.

Prior to joining my Ph. D, I worked as an Assistant Professor at Galgotias College of Engineering and Technology (A. K. T. U) for 2.5 years. I completed my Masters in Computer Science and Engineering with two gold-medals from Aligarh Muslim University (A. M. U), India, 2016 and Bachelors in Computer Engineering from Aligarh Muslim University (A. M. U), India, 2014.
