M.S., Geotechnical Engineering, Tongji  University, China

B.S., Civil Engineering, Chongqing University, China.

I joined Dr. Xiao's research team in August 2025 as a doctoral student. I plan to use my strong theoretical background to study climate resilience and adaptation of civil infrastructure. My current research is to develop risk assessment, forecasting, and decision-support tools in the North Slope Borough communities considering the risks of permafrost thawing, flooding, and coastal erosion.

B.S., Civil Engineering, Malayer University, Iran

I will join Dr. Xiao's research team in January 2026. My research focuses on using UAS-borne geophysical imaging for permafrost characterization and environmental hazard detection.

Isabel Rubino

Isabel Rubino

Undergraduate student, Civil Engineering, expected graduation: May 2026.

I joined Dr. Xiao's research team in Fall 2022 as a first-year undergraduate student. In 2023, I received the NSF REU award and co-organized a STEM summer camp for middle school students in Utqiaġvik, Alaska, and STEM activities in middle schools in State College, PA. In summer 2024, I returned to Utqiaġvik to co-lead another week-long STEM summer camp for high school students. I led the development of two manuals, “STEM Activities and Lesson Plans” for middle and high school students, and contributed to many STEM-related videos on our YouTube channel: The Changing Arctic. I am passionate about environmental issues under climate change.
