Mehran Sadeghi Lahijani

I am currently a Ph.D student in the Department of Computer Science at Florida State University. I joined Prof. Xin Yuan's group in August 2019. Before that, I was working in Prof. Ashok Srinivasan's research group from September 2016. You can find my CV here.

Research

In August 2019, I had the privilege to join Prof. Xin Yuan's research group (EXPLORER Lab). My new research is about developing secure mechanisms for Datacenters and HPC systems. Currently, our focus is on secure communication in these environments, and my tasks include:
  • Designing a model for predicting the performance of encrypted MPI point-to-point communication on different networks and with various cryptographic libraries.
  • Designing and developing efficient encrypted MPI collective operations.
During my first three years at FSU, I worked as a member of the VIPRA project team under the supervision of Prof. Ashok Srinivasan. VIPRA is an interdisciplinary research project focused on assessing policies that are effective for reducing the likelihood of epidemics. In this project, we are trying to develop an almost real-time decision-support/recommendation system. This software can be used to analyze air-travel policies that can replace air-travel bans during the outbreaks. My tasks in this project were:
  • Developing models for simulation of aircraft passengers' movement using social force models and crowd simulation techniques.
  • Developing architecture-aware models for optimizing the performance of parameter sweeps using CPU and GPU accelerators on supercomputers.
  • Developing fast algorithms for analyzing parameter sweep outputs.
This project has recently been covered in more than 200 news outlets (as of October 2020) all over the world! A list of these reports can be found here.
