About this collection

The JAAS Emerging Investigator Lectureship is given to recognise and support an emerging scientist working in the area of atomic spectrometry in the early stages of their independent career. Researchers are nominated by the community and the winner is chosen by the JAAS Editorial Board based on the originality, quality, impact and significance of the candidate’s research, as highlighted in their nomination. This is a collection of papers authored by previous recipients. 

2021 Recipient

Jacob T. Shelley, Rensselaer Polytechnic Institute, USA

Jacob (Jake) Shelley, Alan Paul Schulz Career Development Professor of Chemistry at RensselaerPolytechnic Institute, earned his B.S. in Chemistry from Northern Arizona University. He completed his Ph.D. at Indiana University under Gary Hieftje where he studied novel plasma ionization sources for molecular mass spectrometry.  Jake did postdoctoral research with Graham Cooks at Purdue University developing portable mass spectrometers capable of in situ analyses.  After another post-doc at the University of Münster, he became Assistant Professor at Kent State University and later moved to RPI in 2016.

His research interests lie in the development of new hardware and software tools for mass spectrometry, which enable rapid, sensitive detection and identification of analytes in complex matrices.  In addition, his research group uses high-energy plasma-generated species to perform unique gas-phase synthesis.  These research areas converge in studying chemical origins-of-life through the Rensselaer Astrobiology Research and Education (RARE) Center, where he is the Associate Director.

Previous recipients include: George L. Donati, Wake Forest Univesity, USA; Marta Costas Rodríguez, Ghent University, Belgium; Márcia Foster Mesko, Federal University of Pelotas, Brazil; Lara Lobo, University of Oviedo, Spain; Gerardo Gamez, Texas Tech University, USA and Sohail Mushtaq, University of Bristol, UK
