Currently he is a professor of Chemistry at the University of��Arizona��in Phoenix.�� As a postdoc in the Precision Laser Diagnostics Lab, his work was concentrated on introducing electro-optically sampled dual-comb spectroscopy to the investigation of combustion byproducts. Deeply intrigued by the potential of dual-comb spectroscopy, especially its prospective role in quantum chemistry, Justin aspires to amalgamate this innovative spectroscopy method with the study of electronic states in future research endeavors. Outside work, his love for the outdoors is evident through his favorite pastime of camping, and he crafts a balanced life by indulging in hobbies such as gardening, crocheting, and woodworking.

Nazanin Hoghooghi received her PhD in Optics from the College of Optics and Photonics (CREOL) at the University of Central Florida. During her PhD in Prof. Peter Delfyett's group, she developed a high-speed linear intensity modulator based on an injection-locked semiconductor laser for analog optical networks. After her PhD, she joined Prof. Ming Wu's group at the University of California-Berkeley, where she developed a low noise millimeter wave source using photonic techniques. She received a Marie Curie fellowship from the European Commission in 2013 and joined the Quantum Sensors Technologies and Applications (QTEA) network. She conducted her research at TOPTICA Photonics in Munich, Germany. She developed two Hz-linewidth cavity stabilized laser systems with relative short term stability of 10^-15 at 1 sec, and an optical link with phase noise cancellation to deliver the light from the Hz-level reference lasers to a home-built difference frequency generation (DFG) frequency comb. This enabled the first in depth characterization of a DFG frequency comb. Nazanin moved to �鶹ӰԺ with her husband in summer 2015. She joined the Precision Laser Diagnostics group in January, where she is working on highly sensitive frequency comb systems for the detection of hazardous trace gases.

Caroline Alden is a research scientist at CIRES. She is working with Greg Rieker at CU, and Colm Sweeney at the NOAA/ESRL Carbon Cycle Group to detect leaks of methane and other hydrocarbons during natural gas production and distribution, through inverse modeling of trace gases observed by open path frequency comb lasers. Prior to CIRES, Caroline was a postdoctoral fellow at Stanford University, working with Prof. Noah Diffenbaugh on connecting climate extremes in the Amazon Basin to variations in net biosphere exchange of CO2 with the atmosphere. Caroline earned a Ph.D. in Geology from the University of Colorado, �鶹ӰԺ in 2013, with Prof. Jim White and Dr. John B. Miller (NOAA/ERSL), for her work developing an inversion framework for��13C of atmospheric CO2, and exploring its potential as a tracer for regional drought stress in North America. She has also published work on global CO2 sink strength and on atmospheric 13CO2 as a potential indicator of global terrestrial carbon exchange, water stress, and partitioning C3/C4 plant productivity. Caroline’s love of exploring the outdoors led her to pursue arctic field geology at Colorado College, which led to an interest in climate change research and, eventually, the pursuit of techniques for interpreting the signals and signs left by nature and humans in atmospheric greenhouse gases.
