Srinivas Vanapalli’s  academic roots are from the Indian Institute of Technology, Madras with a bachelor degree in Mechanical Engineering. He later received an electrical engineering  master’s degree (cum laude) from the University of Twente. He received his PhD title for 'High frequency operation and miniaturization aspects of cryocoolers' at UT, a major part of this work is carried out at the National Institute of Standards and Technology, Boulder, USA.

Srini has a mix of industrial and academic experience and has worked so far in three continents. His research interest is cryogenics where disciplines thermodynamics, material sciences, fluid, and heat transfer meet. He received the 2019 Mulholland award for excellence in cryogenic engineering which is given to recognize significant achievement in a particular areas of cryogenics.

Srini leads the Applied Thermal Sciences lab within the Energy Materials and Systems cluster where his team explores fundamentals and applications of thermal sciences in both space and time domains. The core competence of his group is heat and mass transfer phenomena in the cryogenic temperature range from 200 K to 4 K.  His approach combines formulation of conceptual models, experiments, and numeric. The topics of his research are problem-driven and his team seek to solve grand societal challenges related to energy and life sciences.

Research profiles

What defines me as a teacher?

  • Experiment with better ways to achieve success
  • Value the students and respect them.
  • Inspire students by drawing parallels between the subject matter and students everyday experiences. Also walking through several examples.
  • Belief in mentoring students and showing them the path to learn themselves.
  • Provide thought provoking examples (not just a text book).

Courses in the current academic year are added at the moment they are finalised in the Osiris system. Therefore it is possible that the list is not yet complete for the whole academic year.

My research is supported by national, european funding agencies and industry. 

Funding entities: NWO-TTW, EU, TKI-HTSM, TKI-Energy, ZonMW, ESA & Air Liquide

What drives me as a scientist is the exciting wealth of knowledge and surprises I come across in my research, either in the lab or in discussions with my team. We built a little cryogenic fluids playground and often me and my students try things out of curiosity, very often transforming into serious multi-year projects. I believe in sharing this curiosity with the general public and to high-school students, with a hope to ignite the STEM flame in them. My outreach efforts were recognized recently by the MESA+ Dave Blank Outreach Award.
