Sai Krishna Mulpuri was born in Andhra Pradesh, India, in 1995. He pursued his Bachelor of Technology (B.Tech) in Electrical and Electronics Engineering at the National Institute of Technology (NIT) Warangal, India from 2012 to 2016. His bachelor's thesis focused on the design of an interleaved buck converter for fast PWM dimming of high-brightness LEDs. He completed his Master of Technology (M.Tech) at National Institute of Technology (NIT) Rourkela, India from 2018 to 2020, where he worked on photovoltaic (PV) systems, developing a PV-based smart battery charger with MPPT using a SEPIC converter and implementing nature-inspired meta-heuristic optimization techniques for maximum power point tracking (MPPT) under partial shading conditions. He also designed a fuzzy logic-based MPPT controller for solar arrays under constant weather conditions. From 2021 to 2024, he pursued his Doctor of Philosophy (Ph.D.) at the Indian Institute of Technology (IIT) Guwahati, India as a Prime Minister’s Research Fellow. His research focused on electric vehicle (EV) battery testing and end-of-life assessment, lithium-ion battery electrochemical modeling, cloud-based battery test bed development for life cycle and performance evaluation, and the design of an intelligent battery management system (IBMS) with end-edge-cloud connectivity.

He worked as a General Manager at Trident Group, India from 2016 to 2017, leading energy conservation projects and energy audits. His responsibilities included analyzing steam and electricity consumption, identifying energy-saving opportunities, and overseeing power plant operations, including boiler operations, AHP, and CHP through DCS and PLC. He was responsible for the instrumentation and erection of Trident Energy Budhni’s power project and coordinated with design consultants, vendors, and contractors for project execution.

Since February 2025, he has been working as a researcher at the University of Twente, Netherlands on the "FreeTwinEV" project, focusing on the development of digital twin technologies for EV batteries to improve performance and reliability. His research interests include electric mobility, EV charging, lithium-ion battery modeling, lithium-ion battery ageing and degradation studies.
