We CARE about the ground our infrastructure stands on

The Geo-CARE Laboratory, in the School of Civil, Environmental, and Infrastructure Engineering at Southern Illinois University Carbondale, develops geotechnical solutions for resilient, sustainable infrastructure, from the soils beneath roads, levees and foundations to the subsurface that supplies clean energy and critical minerals.

3D-printed soil materials
Post-wildfire geohazards
Critical minerals from geothermal brines
CO₂ sequestration
Freeze–thaw durability

Our work develops sustainable 3D printing materials from locally available soils, analyses post-wildfire geohazards, and builds integrated frameworks for extracting critical minerals from geothermal brines in support of clean energy and resource sustainability. The lab also investigates CO₂ sequestration strategies within geothermal systems to mitigate emissions and improve renewable resource utilization, alongside freeze–thaw durability in cemented soils.

We welcome motivated students, scholars, and postdoctoral researchers to join an interdisciplinary team working at the intersection of infrastructure resilience, innovative materials, and subsurface resource management. If that describes you, read through the site and write to Dr. Nitin Tiwari with your CV.

Courses taught 6Fall 2026 current

I felt like this is my best class because he actually explains things and sets expectations properly.

CE 320Soil Mechanics

Dr. Tiwari is hands down the best professor I have ever had in my time at SIU. The amount of pride this man takes in his job is off the charts. He cares for his students more than I felt like we deserved at times. I came into his CE 320 class not super interested in his course subject, but after taking this class, I now have developed an appreciation for soil mechanics and foundation design. I truly do not think that there is anyone who loves their job (and soil) more than Dr. Tiwari. He will definitely be one of the best professors I have ever had the pleasure of meeting.
