Abdullah Al-Mamun
I am a Ph.D. candidate in the Department of Computer Science at Purdue University, advised by Professor Walid G. Aref. My research interest is in the area of Database Systems + Machine Learning (ML): “ML for Systems” and “Systems for ML”. I have also been fortunate to engage in research collaboration with Professor Jianguo Wang and Professor Chunwei Liu.

Research
My current research is in the area of “ML for Systems”, particularly focusing on Instance-Optimized Learned Indexes for Multi- and High-Dimensional Spaces. Previously, I was involved in a research project on In-Memory Graph-Relational Data Systems. Additionally, I conducted research on Anomaly Detection from sensor data streams during my graduate studies (advised by Professor Antonina Kolokolova) at Memorial University of Newfoundland, Canada.
