DESCRIPTION:Peter Maurer is an Assistant Professor at the University of Ch
 icago. Peter received his PhD from Harvard\, where he worked with Misha Lu
 kin on NV centers in diamond. One of the projects Peter led as a graduate 
 student was the development of a diamond nano-thermometer\, which enabled 
 measurements of temperature profiles in living cells. The idea of utilizin
 g quantum sensors to probe and manipulate biological systems has motivated
  Peter to complete his postdoctoral training with Steven Chu at Stanford\,
  where he developed luminescent nano-probes for electron microscopy. Now a
 t the University of Chicago\, Peter is combining the tools of quantum engi
 neering\, biophysics\, and materials engineering that he learned during hi
 s PhD and postdoctoral training to develop biocompatible quantum sensing t
 ools and apply them to real-world problems in the life sciences. \nQuantu
 m metrology enables some of the world's most sensitive measurements with p
 otentially far-reaching applications in the life sciences. Although the ul
 trahigh sensitivity of qubit sensors has sparked the imagination of resear
 chers\, implementing them in actual devices that enable monitoring cellula
 r processes or detecting diseases remains largely elusive. Overcoming the 
 limitations that hinder the broader application of quantum technology in t
 he life sciences requires advances in both fundamental science and enginee
 ring. In this talk\, I will discuss new strategies that combine quantum en
 gineering and molecular biology to develop a new generation of quantum sen
 sors that can be readily integrated with biological systems. My discussion
  will start with the development of a novel biocompatible surface function
 alization architecture for highly coherent diamond crystals. I will then c
 ontinue with discussing a new approach to engineering spin coherence in co
 re-shell structured diamond particles\, which can be readily chemically mo
 dified and delivered to intact biological systems. Finally\, I will depart
  from established diamond sensors and introduce an entirely new class of b
 iological qubits based on optically-addressable spins in fluorescent prote
 ins. These protein-qubits have coherence times and optical readout compara
 ble to solid-state defects\, but are only 3 nm in diameter and genetically
  encodable. The unifying theme of these advances is the convergence of tec
 hniques from quantum engineering and molecular biology. Specific applicati
 ons of the developed sensing platforms to questions in the life sciences w
 ill be discussed throughout this talk.
