Short Biography
Maloy Kumar Devnath, is a Ph.D. student in the Information Systems Department at the University of Maryland Baltimore County. His current research focuses on comprehending the melting patterns of sea ice and investigating its implications on the melting of land ice, which is a key factor contributing to the rising sea levels. Maloy is conducting his research in the Artificial Intelligence/Machine Learning area under the supervision of Dr. Vandana P. Janeja and Dr. Sudip Chakraborty. His academic journey began with a BSc degree, and he briefly worked as a Software Developer at Code Crafters International Limited. Following his passion for education, he transitioned to an academic role as a Lecturer at Bangabandhu Sheikh Mujibur Rahman Science & Technology University, Gopalganj. He is proud to share that, on June 3, 2022, he was promoted to Assistant Professor, reflecting his dedication to teaching.
Research Summary
Maloy’s research explores the rapid changes happening in Antarctica, where both sea ice and land ice are melting at increasing rates. He studies how the loss of sea ice, which normally protects ice sheets from warmer ocean water, might be contributing to faster land ice melt. Using satellite data and machine learning, Maloy identifies unusual melting events and tracks when they begin, how long they last, and where they occur. He also examines how often sea ice retreat and land ice melt happen together, especially in regions showing early melting and delayed recovery. This work helps improve our understanding of how these changes in Antarctica contribute to rising sea levels around the world.

Abstract
- Understand how anomalous melt events and variations in melt onset and melting period length impact the dynamics of sea ice retreat.
- Assess the significance of anomalous melt events compared to steady-state conditions in influencing sea ice retreat.
- Quantify feature similarity and associations (co-occurrence) between sea ice retreat and land ice or ice sheet melting in regions experiencing anomalous melts, with particular attention to earlier retreat and late accumulation periods.
By addressing these questions, this thesis contributes to a comprehensive understanding of the intricate interactions between sea ice retreat and ice sheet melting in the Antarctic region and their broader implications for global sea-level rise.
