Overview

What is he best known for?

The fields of study he is best known for:

  • Amino acid
  • Hydrogen
  • Biochemistry

His scientific interests lie mostly in Photochemistry, Excited state, Chromophore, Singlet state and BLUF domain. His Photochemistry research includes themes of Photoreceptor protein, Ultrafast laser spectroscopy, Protonation, Fluorescence and Ground state. He studied Excited state and Xanthophyll that intersect with Chlorophyll fluorescence and Photoprotection.

His Chromophore research incorporates elements of Chloroplast relocation, Dark state and Isomerization. John T. M. Kennis has researched Singlet state in several fields, including Rhodobacter sphaeroides, Triplet state, Light-harvesting complex and Double bond. His BLUF domain research integrates issues from Flavin adenine dinucleotide, Biophysics, Stereochemistry and Electron transfer.

His most cited work include:

  • Identification of a mechanism of photoprotective energy dissipation in higher plants (675 citations)
  • Ultrafast transient absorption spectroscopy: principles and application to photosynthetic systems. (367 citations)
  • An unusual pathway of excitation energy deactivation in carotenoids: Singlet-to-triplet conversion on an ultrafast timescale in a photosynthetic antenna (243 citations)

What are the main themes of his work throughout his whole career to date?

John T. M. Kennis spends much of his time researching Photochemistry, Chromophore, Excited state, Fluorescence and Ultrafast laser spectroscopy. His work carried out in the field of Photochemistry brings together such families of science as Triplet state, Singlet state, Quenching and Carotenoid. In his study, which falls under the umbrella issue of Carotenoid, Orange carotenoid protein is strongly linked to Photoprotection.

His Chromophore study also includes fields such as

  • Wild type most often made with reference to Quantum yield,

  • Photoreceptor protein which is related to area like Biophysics,

  • Hydrogen bond that connect with fields like Stereochemistry. His study on Excited state also encompasses disciplines like

  • Rhodobacter sphaeroides which is related to area like Flavin adenine dinucleotide,

  • Xanthophyll that intertwine with fields like Chlorophyll fluorescence. His study in Ultrafast laser spectroscopy is interdisciplinary in nature, drawing from both Molecular physics, Internal conversion and Femtosecond.

He most often published in these fields:

  • Photochemistry (63.50%)
  • Chromophore (27.74%)
  • Excited state (27.74%)

What were the highlights of his more recent work (between 2015-2021)?

  • Photochemistry (63.50%)
  • Excited state (27.74%)
  • Biophysics (16.79%)

In recent papers he was focusing on the following fields of study:

His main research concerns Photochemistry, Excited state, Biophysics, Femtosecond and Chromophore. His Photochemistry research is multidisciplinary, incorporating elements of Stimulated raman, Ultrafast laser spectroscopy and Amide. His Excited state research incorporates elements of Chemical physics, Ground state and Chlamydomonas reinhardtii.

The various areas that John T. M. Kennis examines in his Biophysics study include Orange carotenoid protein, Photosystem II and Physcomitrella patens. His Femtosecond course of study focuses on Photoprotection and Conformational isomerism, Molecular vibration and Protein secondary structure. His studies deal with areas such as Phototropin and Fluorescence as well as Chromophore.

Between 2015 and 2021, his most popular works were:

  • Photoactivation Mechanism, Timing of Protein Secondary Structure Dynamics and Carotenoid Translocation in the Orange Carotenoid Protein (33 citations)
  • Unfolding of the C-Terminal Jα Helix in the LOV2 Photoreceptor Domain Observed by Time-Resolved Vibrational Spectroscopy. (31 citations)
  • The photochemistry of sodium ion pump rhodopsin observed by watermarked femto- to submillisecond stimulated Raman spectroscopy (29 citations)

In his most recent research, the most cited papers focused on:

  • Amino acid
  • Hydrogen
  • Biochemistry

The scientist’s investigation covers issues in Femtosecond, Chlamydomonas reinhardtii, Crystallography, Excited state and Photochemistry.
