Zusätzliche Informationen
Forschungsgebiet
PD Dr. Naresh Kumars Forschung konzentriert sich auf die Entwicklung und Anwendung optischer Nanospektroskopie und Nanoimaging. Insbesondere entwickelt er AFM- und STM-basierte plasmonenverstärkte optische Spektroskopietechniken – darunter Raman-, Fluoreszenz- und Photolumineszenzspektroskopie – um hyperspektrale molekulare und chemische Bildgebung auf der Nanoskala zu ermöglichen. Dr. Kumar wendet diese hochmodernen nanoanalytischen Methoden in einem breiten Spektrum von Forschungsbereichen an, darunter katalytische Materialien, Biomaterialien, polymere Systeme, photovoltaische Materialien sowie zweidimensionale Materialien wie einkristallines Graphen und Übergangsmetall-Dichalcogenide. Darüber hinaus untersucht er chemische Umwandlungen an kristallinen Metalloberflächen und Fest-Flüssig-Grenzflächen auf der Nanoskala.
Lebenslauf
PD Dr. Naresh Kumar ist habilitierter Dozent (Privatdozent) für optische Nanospektroskopie und Nanoimaging am Departement für Chemie und Angewandte Biowissenschaften (D-CHAB) der ETH Zürich, wo er seit 2020 tätig ist.
Er erwarb seinen Bachelor of Technology in Engineering Physics am Indian Institute of Technology Delhi und schloss seinen Master of Research in Physics at the Nanoscale mit Auszeichnung am King’s College London ab. Seine Promotion absolvierte er an der Universität Utrecht (Niederlande) unter der Betreuung von Prof. Bert Weckhuysen mit dem Schwerpunkt auf der Entwicklung der Tip-Enhanced Raman Spectroscopy (TERS) und deren Anwendung in der heterogenen Katalyse.
Im Jahr 2011 trat Dr. Kumar als Research Scientist in das National Physical Laboratory (NPL), Großbritannien, ein, wo er die Entwicklung und Anwendung von TERS maßgeblich vorantrieb. Er etablierte ein hochmodernes AFM-basiertes TERS-System am NPL, das fortschrittliche spektroskopische Untersuchungen auf der Nanoskala in zahlreichen interdisziplinären Forschungsprojekten ermöglichte. Seine Arbeit erstreckt sich über verschiedene wissenschaftliche Bereiche, darunter heterogene Katalyse, organische Solarzellen, Polymermischungen, chemisches Imaging an Fest-Flüssig-Grenzflächen sowie 2D-Materialien wie Graphen und Monolagen-MoS₂. Für seine wissenschaftlichen Leistungen wurde Dr. Kumar 2016 mit dem renommierten Rayleigh Early Career Award des NPL ausgezeichnet und 2017 zum Higher Research Scientist befördert.
Dr. Kumar ist ein gefragter eingeladener Sprecher auf internationalen wissenschaftlichen Konferenzen. In Anerkennung seiner Expertise wurde ihm von 2020 bis 2023 eine Visiting Professorship an der School of Sciences der Hangzhou Dianzi University (China) verliehen. Im Jahr 2023 wurde er mit dem angesehenen Masao Horiba Award für seine Fortschritte in der optischen Nanospektroskopie zur Untersuchung neuartiger Halbleitermaterialien ausgezeichnet.
