Lee designs and builds large-format TES bolometer arrays and their SQUID-multiplexed cryogenic readout electronics for the South Pole Telescope and CMB-S4, working to push per-detector noise toward the fundamental photon-noise limit for next-generation cosmic microwave background polarization surveys.

Leon-Saval co-invented the photonic lantern and is the fibre-device engineer of the SAIL programme. His group designs, draws and characterises multicore fibres, mode-selective lanterns, OH-suppression fibre Bragg gratings and hexabundles, and increasingly applies the same devices outside astronomy — in telecommunications space-division multiplexing and in medical endoscopy and imaging through fibre. The unifying technical problem is coupling a spatially-incoherent, aberrated beam into single-mode circuitry without losing photons. Positioned against the established body of NV-ensemble quantum sensing work — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — photonic lanterns are directly applicable to quantum sensing readout: the same device that feeds a seeing-limited telescope beam into a single-mode spectrograph can feed fluorescence from a scattering biological sample into a single-mode quantum-limited detector, preserving the photon budget that a pT/sqrt(Hz) NV measurement depends on.

Studies active galactic nuclei, supermassive black hole binaries, and time-domain phenomena using large optical/IR spectroscopic and imaging surveys.

Directs the Laboratory for Astronomical Imaging; develops millimeter/submillimeter interferometric imaging instrumentation (e.g., for ALMA) and studies star and protoplanetary disk formation.

Astroparticle physicist searching for sources of ultrahigh-energy cosmic particles with IceCube and developing next-generation astroparticle/neutrino detector instrumentation.

Madhusudhan pioneered inverse 'atmospheric retrieval' techniques to determine the chemical composition, interior structure and formation history of exoplanets from their spectra, including recent JWST-based investigations of potential biosignature gases on temperate sub-Neptunes (Hycean worlds).

Maiolino investigates the formation, evolution and transformation of galaxies and black holes, with a current focus on the discovery and characterisation of massive black holes and Pop III star signatures in the early Universe using JWST/NIRSpec; he is also Project Scientist for the MOONS multi-object spectrograph (VLT) and the ANDES high-resolution spectrograph (ELT).

Markoff studies the extreme physics of accretion and jet formation around black holes of all scales, combining multi-wavelength observations with computational simulations; she is a founding member of the Event Horizon Telescope collaboration that produced the first black hole images, and co-leads a new EHT station in Namibia.

Marshall builds astronomical spectrographs and calibration systems in the Munnerlyn Lab; co-PI of GMACS (Giant Magellan Telescope) and project scientist for the Maunakea Spectroscopic Explorer, leading instrumentation for DES and HETDEX. Astronomy pivot driven by high-precision spectral/photometric instrumentation.

Studies galaxy formation and evolution using spectroscopic surveys of high-redshift galaxies with JWST and other facilities.
