Congratulations to Mr. Arunesh Mishra upon his graduation

The REAPER Lab congratulates Mr. Arunesh Mishra upon his graduation from Texas A&M University with a Master of Science in Computer Engineering. Mr. Mishra joined the REAPER Lab while completing his graduate studies and thesis research. He was co-advised by Dr. Duncan M. “Hank” Walker (Computer Engineering) and Dr. Robert S. Balog (Electrical Engineering). His research focused on a software platform for designing, validating, and documenting hardware-in-the-loop and hardware test systems. The platform allows engineers to visually model test setups, define hardware connections and signal mappings, identify potential design errors, and automatically generate engineering documentation.

Congratulations to Ms. Poornima Gulur Chakrapani upon her graduation.

The REAPER Lab congratulates Ms. Poornima Gulur Chakrapani upon her graduation from Texas A&M University with a Master of Science in Electrical and Computer Engineering. Ms. Chakrapani joined the REAPER Lab in 2024. She earned her B.E. in Electronics and Communication Engineering from BNM Institute of Technology, India. Her research focused on developing a rapid prototyping workflow for FPGA-based Model Predictive Control (MPC) using MATLAB/Simulink, HDL Coder, Intel Quartus, and Typhoon HIL. Her research developed a complete workflow for rapidly prototyping FPGA-based Model Predictive Control (MPC), integrating MATLAB/Simulink, HDL Coder, Intel Quartus, and Typhoon HIL from controller design to real-time hardware validation. Ms. Chakrapani will be joining Apple as a SoC Physical Design Engineer in San Jose, California.

Thesis Defense: Ms. Poornima Gulur Chakrapani.

REAPER Lab congratulates Ms. Poornima Gulur Chakrapani for successfully defending her M.S. thesis entitled, “A Developmental Workflow for Rapid Prototyping of FPGA-Based Model Predictive Control (MPC),” on June 10, 2026. Ms. Chakrapani’s research developed a rapid prototyping workflow for FPGA-based Model Predictive Control (MPC) in power electronics applications. She implemented the controller using MATLAB/Simulink, HDL Coder, Intel Quartus, and Typhoon HIL, with a focus on fixed-point implementation and FPGA resource optimization through significant Adaptive Logic Module (ALM) reduction.

Ms. Chakrapani earned her B.E. in Electronics and Communication Engineering from BNM Institute of Technology, India, and completed her M.S. in Computer Engineering at the REAPER Lab at Texas A&M University. She will be joining Apple as a SoC Physical Design Engineer in San Jose, California.

Thesis Defense: Mr. Arunesh Mishra.

The REAPER Lab congratulates Mr. Arunesh Mishra for successfully defending his M.S. thesis entitled, “BOSELOOP: A Design and Validation Platform for Hardware-in-the-Loop Test Systems.” Mr. Mishra’s research addressed the challenges associated with planning, validating, and documenting complex hardware test systems. He developed a graph-based engineering platform that enables users to visually construct hardware setups, define ports and signal connections, perform automated design checks, and generate documentation such as channel-mapping sheets, and bills of materials. His work demonstrates how software-assisted design and validation can reduce manual engineering effort, improve documentation consistency, and identify integration issues before physical test systems are assembled.

Mr. Mishra earned his B.S. in Computer Engineering from the University of Cincinnati in 2023 and completed his M.S. in Computer Engineering at Texas A&M University in 2026. His professional experience includes hardware validation and embedded engineering work at Tesla, John Deere, and Volvo Trucks. He is continuing his work in hardware validation for broader use by engineering teams. Mr. Mishra was co-advised by Dr. Duncan M. “Hank” Walker (Computer Engineering) and Dr. Robert S. Balog (Electrical Engineering).

Vijay Kumar, Vildan Turan, and Sakshi Batawale toured the Eaton Experience Center in Houston.

REAPERlab graduate students Vijay Kumar, Vildan Turan, and Sakshi Batawale toured the Eaton Experience Center on April 10, 2026 in Houston, Tx USA. Arranged by the Texas A&M University IEEE IAS, PES, PELS joint student branch chapter, participants saw first hand various aspects of the modern electrical systems including a mock petrochemical refinery, a substation with a power distribution grid, and microgrid with distributed energy resources. Experiential learning helps to “ground” theory from the textbook to practical implementation using real-world equipment.

Vijay Kumar K presents research paper at the 2026 IEEE Texas Power and Energy Conference (TPEC)

Ph.D student Vijay Kumar K presented his paper entitled “Assessing the Impact of Smart Inverters on Voltage Regulator Actuations using OpenDSS and MATLAB” at the 10th IEEE Texas Power and Energy Conference (TPEC) held on February 8-10, 2026 in College Station, Tx USA.

This paper investigates the potential for adverse interactions between smart photovoltaic (PV) inverters and conventional voltage regulators in electric distribution systems. Multiple operating scenarios are developed and analyzed using a simulation-based methodology designed to quantify the impact of smart inverter operation on voltage regulator performance. The IEEE 123-bus test feeder, configured with seven voltage regulators, is modeled in OpenDSS-G and integrated with three PV inverters. Six scenarios are examined, ranging from a baseline case with no PV to configurations including mixed smart and conventional inverters and a fully smart-inverter deployment. Time-series simulations are conducted over a 24-hour period with 10-minute resolution, and the resulting data are exported for post-processing and analysis. The findings provide insight into future strategies for coordinated inverter–regulator control.

Dr. Ibrahim Guneş presents research paper at the 2026 IEEE Texas Power and Energy Conference (TPEC)

Dr. Ibrahim Guneş, visiting scholar in the REAPERlab from Istanbul University – Cerrahpaşa, presented his paper entitled “Comparison of Performance for Floating Photovoltaic (FPV) and Ground-Mounted PV Systems” at the 10th IEEE Texas Power and Energy Conference (TPEC) held on February 8-10, 2026 in College Station, Tx USA.

The study presents a comparative evaluation of floating photovoltaic (FPV) systems and conventional ground-mounted PV installations. The research systematically analyzes key performance metrics including energy yield, module operating temperature, conversion efficiency, performance ratio, and site utilization characteristics under comparable environmental conditions. The results demonstrate that FPV systems exhibit measurable thermal advantages due to the natural cooling effect of water bodies, leading to improved module efficiency and enhanced energy output in specific operating regimes. In addition to performance analysis, the study addresses practical considerations such as installation constraints, environmental interactions, maintenance requirements, and long-term operational reliability. This contribution advances the technical understanding of alternative photovoltaic deployment strategies and supports informed decision-making for sustainable and optimized solar energy integration.
