Directs the Wisconsin IceCube Particle Astrophysics Center (WIPAC); works on IceCube and next-generation neutrino telescope instrumentation for high-energy astroparticle physics.
Observational high-energy astrophysicist studying black hole X-ray binaries, relativistic jets, and their impact on surrounding gas using X-ray, optical, and radio observations.
Develops scalable, atomically-precise low-dimensional (2D/1D/0D) materials and heterostructures, focusing on single-photon emitters and spin defects in semiconductors for quantum sensing and molecular-based qubits.
Studies molecular and nano-optics, plasmonics, and near-field light-matter interactions, using super-resolution optical imaging to reveal active sites and phase transformations in heterogeneous catalysis and single nanodomains.
PREFERRED. Ji is launching the Ji Quantum Lab at MIT to build next-generation scanning-probe and on-chip quantum sensors (millimeter-wave impedance microscopy, 'RFlexiScope') that map nanoscale conductivity, magnetism and collective excitations in strongly correlated and topological quantum materials down to the quantum limit. The lab is explicitly recruiting PhD students, postdocs, and UROPs as of its founding.
Theoretical and phenomenology-driven particle physicist working on dark-matter detection concepts, including collaboration on experimental efforts using organic scintillators for directional/anisotropic dark-matter detection.
Studies compact objects (neutron stars, white dwarfs) via precision timing measurements and uses existing and new radio arrays to explore the time-domain radio sky.
Studies light-matter interaction at the nanoscale (metasurfaces, thermal emission, plasmonics) and, with Jennifer Choy, has developed metasurface polarizing beamsplitters that enable compact, chip-integrated atomic magnetometers (optically pumped magnetometry) alongside broader work in quantum and topological photonics.
Radio astronomer working on very-long-baseline interferometry (VLBI) and radio imaging instrumentation, including maser and stellar-envelope studies and computational methods for radio astronomy.
Studies the physical rules governing bacterial gene expression using single-molecule and quantitative live-cell imaging approaches.
