About
Bio
Dr. Isabel Harrysson Rodrigues is a nanotechnology scientist specializing in developing state-of-the-art microdevices, such as electrical components for sensing and detection. Her current research focuses on designing and fabricating robust III-V material-based microdevices for the extreme environments found in space.
Currently, Isabel Harrysson Rodrigues is a Postdoctoral Research Fellow at JPL, NASA, collaborating with Dr. Mina Rais-Zadeh's group (at JPL) in the Microdevices and Sensor Systems’ Microdevice Laboratory, where they are developing sensors and detectors for harsh space environments, such as elevated temperatures (< 600 deg C) and intense radiation. Their components will be used mainly for thermal sensing at the surface of Venus and gathering information for future missions to yet-unexplored planetary bodies.
In addition, Isabel is also working on a project in Matthew Shaw's group, where she is developing the readout chain for their superconducting nanowire single-photon detectors (SNSPDs) in a project they called PEACOQ - Performance-Enhanced Array for Counting Optical Quanta.
While earning valuable experience during her research visit at Stanford University, in David Goldhaber-Gordon's Group, and her Ph.D. from Chalmers University of Technology, Isabel Harrysson Rodrigues worked on various device fabrication techniques, as well as development and performance of these devices, mainly high electron mobility transistors (HEMTs) and 2D-materials, such as AlGaAs/InP HEMTs and twisted bilayer graphene, including hexagonal boron nitride. She spent numerous hours in high-quality cleanroom facilities fabricating microdevices for various applications, such as low-noise amplifiers, terahertz biosensing, and fundamental research in carrier transport, spintronics, and superconductivity. She also worked on simulations of electron transport, analysis of charge carrier defects affecting device performance, and data analysis of the DC characteristics in various transistor configurations, all pivotal parts of her thesis.
Before her move to the US, she also worked at Ericsson AB in Gothenburg, developing the next-generation 6G platform, which required advanced PCB design, RF measurements, and rigorous verification schemes for communication.
When not involved in research, Isabel Harrysson Rodrigues has pursued sports and art in her spare time, playing high-level soccer for many years and representing Sweden in the national team of footvolley until her move to the US (2023). Staying mentally and physically healthy has always been a consistent interest in her life, where making art has constituted her time to relax and unwind. Upon encouragement to share her art, she created a webpage to display some of her pieces: www.isabelharryssonrodrigues.com. Other key ingredients in her life are spending time with family and loved ones, including her dog, preferably outdoors in the forest or by the beach.
