Dr. Sergei Gronin
Dr. Sergei Gronin obtained his PhD from the Ioffe Institute of Saint-Petersburg, Russia, developing MBE grown of low threshold lasers based on II-VI materials for green and yellow spectral region. Prior to joining Professor Manfra’s group as part of Microsoft Quantum Purdue in May, 2017 he was a Junior Researcher in the Laboratory of Quantum-size heterostructures (head. Professor Sergey Ivanov) at Ioffe Institute. As part of Microsoft Quantum Purdue, Dr. Gronin develops MBE growth for heterostructures of superconductors and highly spin-orbit coupled III-V semiconductors.
Calvin Freed
Calvin joins Professor Manfra’s research team from the University of Illinois at Urbana-Champaign as a Purdue University engineering intern beginning in May of 2024. With the Quantum Semiconductor Systems Group, he will apply and further develop his engineering skills in support of MBE growth equipment and labs.
Dr. Raymond Kallaher
Dr. Kallaher received his PhD from Florida State University in 2007, studying the ferromagnetic semiconductor europium sulfide. Prior to joining Professor Manfra’s group as part of Microsoft Quantum Purdue in 2017, Dr. Kallaher was a Senior Scientist at Modern Microsystems working on process development for fabricating high power electronic devices and x-ray optics. He has held postdoctoral research positions at Virginia Tech, studying spin coherent transport in indium antimonide and indium arsenide systems, and at the National Institute of Science and Technology, researching nanostructured thermoelectric materials. As part of Microsoft Quantum Purdue, Dr. Kallaher develops device microfabrication processes for heterostructures of superconductors and highly spin-orbit coupled III-V semiconductors.
