My Short Bio

My name is Praveen Kumar, and I currently work as a Research Assistant Professor at the School of Medicine, University of New Mexico (UNM).

I hold a Bachelor’s degree in Computer Engineering from the National Institute of Technology (NIT) Surat, and both a Master’s and Ph.D. in Computer Science from the University of New Mexico (UNM), Albuquerque, USA. Following my undergraduate studies, I spent 12 years in the IT industry, working across the banking, insurance, and travel sectors in roles such as Software Engineer, Systems Analyst, and Associate Project Manager. However, my passion for artificial intelligence (AI) and machine learning (ML) led me to transition into academia. I returned to graduate school to pursue advanced studies, culminating in a Ph.D.

My research expertise spans health informatics and cheminformatics, with a focus on developing AI/ML algorithms to extract insights from complex, noisy, and high-dimensional datasets. This includes working with patient health records, chemical compound data, and biomedical knowledge graphs. In health informatics, I develop methods to identify mental health conditions and co-occurring disorders from EHR and claims data. In cheminformatics, my work centers on discovering potential therapeutic compounds by analyzing chemical datasets. I also work on biomedical knowledge graphs to infer associations between biological entities such as genes and diseases. Recently, I have been developing ML-based risk models for the early detection of cardiometabolic diseases.

Beyond my academic research, I have experience in teaching and mentoring, primarily gained during my time in the IT industry, where I was responsible for training new team members in both technical skills and domain-specific knowledge. I also hold certifications in Equity Derivatives and Mutual Funds from the National Stock Exchange (NSE) of India.
