I joined the Organic Electronics group of Dr. Denis Andrienko at the Max Planck Institute for Polymer Research (MPI-P) as a postdoctoral fellow in autumn 2023 to study acceptor materials for organic solar cells.
I obtained my PhD at the Swiss Federal Institute of Technology - Lausanne (EPF/ETH Lausanne, Switzerland) in 2023, working on the data-driven design of materials for organic electronics applications in the group of Prof. Clémence Corminboeuf. I employed database curation, machine learning, and multiple computational techniques to discover and establish design rules for compounds with unique excited state characteristics, in particular for solar energy and light-emitting diode applications.
I received my MSc at Université Laval (Québec, Canada) as a Schmeelk Canada fellow in 2018, and a BSc from the same institution in 2016 as an inaugural Schulich Leader scholar. There, I worked under the supervision of Profs. Mario Leclerc (polymer chemistry) and Paul Johnson (computational chemistry) on the synthesis of conjugated polymers via C-H bond activation. In 2016-2017, I was awarded a foreign study fellowship from the Natural Sciences and Engineering Research Council of Canada to conduct research for half a year in the group of Alán Aspuru-Guzik at Harvard University (USA).
In addition, I have studied at the Université de Strasbourg (France) and have taught music and science at Gandhi Ashram School in rural northern India.
In 2025, Terry joined the University of Alberta as an assistant professor.

Blue organic light-emitting diodes based on thermally activated delayed fluorescence suffer from low stability and broad emission. Hyperfluorescence—in which the excited state created on the thermally activated delayed fluorescence emitter is transferred to a fluorescent terminal emitter with a narrow emission spectrum—is promising towards improving colour purity and stability. However direct charge trapping on the smaller-gap terminal emitter may lead to direct emissive losses inhibited charge transport and charge imbalance. Here we demonstrate single-layer pure-blue hyperfluorescent organic light-emitting diodes that are not compromised by charge trapping on the terminal emitter. We reveal that the energetic disorder of the thermally activated delayed fluorescence sensitizer allows for the presence of a terminal emitter with a smaller energy gap without affecting charge transport. Consequently the stability benefits of single-layer organic light-emitting diodes can be combined with trap-free hyperfluorescence resulting in pure-blue emission a simple device structure high quantum and power efficiencies and state-of-the-art operational stability.

Discerning loss mechanisms in organic solar cells with narrow optical bandgap is critical for the development of conventional and next-generation photovoltaic technologies especially for tandem and semi-transparent solar cells. Here all photocurrent losses are quantitatively deconvoluted in two low-bandgap (Eg≈1.23 eV) binary systems using structurally analogous non-fullerene acceptors (NFAs) namely BTPV-4F-eC9 and BTPV-4Cl-eC9. Bias-dependent free charge generation and photoluminescence studies pinpoint geminate charge transfer (CT) state recombination as the predominant photocurrent limitation in both systems compared to parent Y6-blends. Transient absorption spectroscopy too reveals a critical competition between CT decay and separation dynamics. Theoretical calculations uncover multiple stable molecular conformers that restrict NFA aggregation aligning with morphological studies resulting in poor CT separation in photoactive blends. Owing to CT loss pathways free charge recombination in both low-bandgap systems is closer to the Langevin limit than in PM6:Y6. Nonetheless they exhibit overall voltage losses of ≈0.56 V comparable to PM6:Y6 and efficient exciton dissociation despite a lower driving force. Current-voltage simulations show that suppressing geminate losses can vitally balance recombination pathways to unlock photocurrent potential of low-bandgap blends. Further optimization of the charge carrier mobility would push the PCE >16\% moving the internal quantum efficiency toward the detailed balance limit.
