KeywordsAssistant Professor Emirate Imaging Mass Spectrometry Postdoctoral Research Focus Section
The health and vitality of any field of research can easily be determined by looking for the work being carried out by its emerging investigators. These investigators bring a vibrant energy to the subject, which infuses into the rest of the community. They also bring new ideas and perspectives that stimulate the development of innovative solutions to existing problems. The “Emerging Investigators” focus section contained within this issue of the Journal of the American Society for Mass Spectrometry (JASMS) highlights the exciting work being carried out by just some of the outstanding young researchers working today in the field of mass spectrometry and, in doing so, also captures emerging high-impact areas of research that have the potential to influence the future directions of our field. The prevalent theme of the research described in the focus section articles is the development and application of bioanalytical mass spectrometry and associated strategies for biomolecular analysis, commensurate with the immense impact that mass spectrometry has had, and continues to have, in solving some of the most difficult challenges facing the biological sciences over the past two and a half decades. Invitations to contribute to the focus section were based on suggestions solicited from the JASMS Editor, Associate Editors, and members of the Editorial Board, and from members of the ASMS Board of Directors. Although no firm criteria were used to distinguish between “emerging” and “established” scientists, the goal was to emphasize the work of investigators within the first 10 years of their independent careers, who, while relatively early in their careers, are already making important contributions to the literature and are expected to become future leaders within the field. Rather than summarizing the research described within these articles, the diverse range of which is immediately evident by scanning the Table of Contents for the issue, a brief biographical sketch is instead provided below to illustrate the diverse backgrounds and paths by which each of the contributing authors have converged upon the field of mass spectrometry, and the overall research interests of their laboratories. I look forward to seeing more of their exciting work in the future.

He earned B.Sc. (2001) and M.Sc. (2003) degrees in Nuclear Physics from the Institute for Applied Science and Technology, Havana, Cuba, and a Ph.D. in 2006 from Pontific Catholic University in Río de Janeiro, Brazil. He then pursued postdoctoral research in the Department of Physical Chemistry at the Federal University of Rio de Janeiro, Brazil from 2006 to 2007 and in the Department of Chemistry at Texas A&M University from 2007 to 2010. From 2010 to 2012, he was a NIH K99 award (2010–2012) prior to joining FIU in 2012. One of the research objectives of the Fernandez-Lima laboratory is the development of fast separation/identification techniques that can be easily implemented for the analysis of complex biological mixtures (e.g., gas-phase, post-ionization separation in ion mobility spectrometry, and mass spectrometry) and the study of the conformational space of molecular ions for structural elucidation.
Stephen J. Valentine received his Ph.D. from Indiana University in 2000 where he worked in David Clemmer’s laboratory. He was one of the first employees of the biotechnology startup company Beyond Genomics, Inc., then later helped found and raise initial funding for the company Predictive Physiology and Medicine, Inc. Returning to academia in 2008, Stephen worked as an Associate Scientist at Indiana University where he assisted Professor David Clemmer in the development of the theory of Overtone Mobility Spectrometry—a new, high-resolution gas-phase separation technique. In 2012, Stephen joined the faculty at West Virginia University as an Assistant Professor in the C. Eugene Bennett Department of Chemistry. Stephen’s current research interests lie in the development of novel ion mobility spectrometry-mass spectrometry (IMS-MS) instrumentation and techniques for the characterization of biomolecular structures in solution and in the gas phase.
Amanda B. Hummon earned her B.Sc. degree in Chemistry at Cornell University. She then completed her Ph.D. graduate research in the laboratory of Prof. Jonathan Sweedler at the University of Illinois, Urbana-Champaign using MALDI mass spectrometry to study neuropeptide processing. Following a postdoctoral fellowship at the National Cancer Institute, she was appointed the Walther Cancer Assistant Professor at the University of Notre Dame in 2009.
