About Me

Ph.D. Researcher | University of Colorado Colorado Springs

I am a Ph.D. researcher with over 9 years of experience in renewable energy systems, specializing in the integration of fuel cell-battery storage in microgrids. My research focuses on developing optimization frameworks for hybrid energy storage systems to achieve zero-emission operation while maximizing renewable energy penetration. I have published over 20 peer-reviewed articles in high-impact journals and conferences, with my work demonstrating significant improvements in system efficiency and cost reduction.

Beyond research, I actively serve the engineering community through leadership roles in IEEE Power & Energy Society, Colorado Renewable Energy Society (CRES), and Colorado Hydrogen Network (CHN). I am particularly interested in expanding my research toward AI/ML-based energy management, resilient power systems, and strategies for 100% renewable penetration.
