Anirudh ChoudharyI am a second year PhD student in ECE at UIUC working with Professor Ravishankar Iyer. I am a part of the DEPEND group at the Coordinated Sciences Lab. My research interests lie in machine learning and probabilistic modeling for biomedical data analysis with emphasis on limited data settings. I collaborate closely with Dr. Aaron Mangold (Mayo Clinic). Previously, I completed my Masters in Computational Science and Engineering at Georgia Tech, where I was a researcher at Biomedical Informatics Laboratory advised by Professor May Wang. My research focused on robust policy learning for clinical decision-making using electronic health records. Additionally, I also got an opportunity to work with Professor Jaydev Desai at RoboMed Lab on image-guided surgery. Earlier, I did my MBA from IIM Calcutta, and completed my undergraduate studies at IIT Kharagpur, where I did my thesis with Prof. Ajoy Kumar Ray on texture-based oral cancer prediction using histopathology images. While at IIT Kharagpur, I pursued summer internships with Prof. Christos Davatzikos (University of Pennsylvania) and Prof. Paolo Fiorini (University of Verona). I have five years of professional experience in developing machine learning models for e-commerce and retail consumer data analysis.Email  /  CV  /  Google Scholar  /  LinkedIn |

K. V. Saboo, A. Choudhary, Y. Cao, G. A. Worrell, D. T. Jones, R. K. Iyer Advances in Neural Information Processing Systems, 2021   We propose a framework for modeling AD progression that combines differential equations (DE) with reinforcement learning (RL). In our model, the available DEs define the simulator and the RL agent optimizes the domain-based reward function in the simulato. rRL combined with the DEs describes the evolution of factors pertinent for modeling AD progression. |

F. Heemeyer*, A. Choudhary*, J. P. Desai (*equal contribution) IEEE International Symposium on Medical Robotics (Georgia Tech), 2020   Image intensifiers, also known as C-arms, are important and low-cost tools for surgeons to guide minimally-invasive procedures. However, image intensifiers suffer from several image distortions, which can be misleading during an automated minimally-invasive surgery. We propose a combination of camera-based tracking system and calibration grid to perform accurate distortion correction. |
