Engineering the Future of Infrastructure

Strengthening America鈥檚 infrastructure starts with innovation 鈥 and one 糖心官网 researcher is helping lead that charge. Dr. Hema Jayaseelan, assistant professor of  at 糖心官网, has received national recognition for pioneering research that could reshape how engineers design, monitor and maintain bridges across the United States and beyond. 

Dr. Hema Jayaseelan.Smarter Models, Safer Bridges

With more than 20 years of structural engineering experience, Jayaseelan has developed advanced analytical models that more accurately predict 鈥減re-stress losses鈥 in concrete bridges 鈥 the gradual reduction of internal tension that weakens structural performance over time. When these losses are miscalculated, bridges can experience deflections, vibrations and cracking that shorten their expected 50- to 75-year lifespan, creating costly and potentially hazardous outcomes. 

Jayaseelan discovered that many traditional Department of Transportation (DOT) formulas overestimate or underestimate pre-stress losses. Her groundbreaking study introduced a data-driven method that uses real-time information from instrumented bridges, producing predictions that closely align with actual field performance. 

National Recognition and Industry Impact

Her peer-reviewed paper, 鈥淎ssessment and Validation of Prestresses Loss Prediction Models Using Real-Time Prestress Loss Measurements,鈥 applied the new method of monitoring bridge data. Coauthored with structural engineering experts Alla Eddine Acheli, Ph.D.; Bruce W. Russell, Ph.D., P.E., S.E., F.A.C.I.; Walter Peters, P.E.; and Chris Filip, the piece was published in the 2024 September to October issue of the PCI journal. The research earned the 2025 Charles C. Zollman Award from the Precast/Prestressed Concrete Institute (PCI), honoring the year鈥檚 best technical paper discussing the use of precast concrete in transportation infrastructure. 

鈥淲e were humbled and grateful to receive the PCI award,鈥 Jayaseelan said. 鈥淚t鈥檚 a blessing and a reminder that God鈥檚 timing is perfect. The recognition shows that DOTs nationwide are beginning to see the importance of this research.鈥 

Her work has also been nominated for the prestigious T.Y. Lin Award from the American Society of Civil Engineers (ASCE), one of the highest honors in global structural engineering. The award celebrates research that advances the science and practice of prestressed concrete design and construction 鈥 a vital component of resilient infrastructure worldwide.

From South India to Smart Bridges

Jayaseelan鈥檚 passion for building began in Coimbatore, South India, where she grew up exploring how structures worked. 鈥淚鈥檝e always loved working with my hands 鈥 playing in the mud, getting dirty. That鈥檚 still what I do today in the lab,鈥 she said. 

After earning her bachelor鈥檚 degree in civil engineering from the Government College of Technology in India and a master鈥檚 degree from Oklahoma State University, Jayaseelan pursued doctoral research at Oklahoma State integrating real-time data from sensors embedded in bridges 鈥 technology she describes as 鈥渓istening to a structure鈥檚 heartbeat.鈥 

These sensors use smart technology, solar power and wireless connectivity to transmit data remotely, allowing engineers to continuously monitor bridge performance. By combining traditional engineering principles with advanced data analysis, Jayaseelan鈥檚 approach creates an early warning system that can detect potential structural issues before they become critical. 

Advancing Global Infrastructure Standards

Her current collaboration with U.S. Department of Transportation officials aims to simplify the new predictive equations for integration into national and international bridge design codes, supporting safer, longer-lasting infrastructure. 

鈥淲e can鈥檛 change everything overnight,鈥 Jayaseelan said. 鈥淏ut through smaller, smarter improvements guided by real-time data and sound engineering, we can make bridges stronger, safer and built to last.鈥 

Jayaseelan鈥檚 research underscores a global movement toward smarter, sensor-integrated infrastructure 鈥 aligning with worldwide efforts to improve sustainability, safety and resilience in public works.
