Research

Jen’s research interests focus on solution-phase synthesis of optical and electronic nanomaterials, including quantum dots and quantum wires. She emphasizes the development of ‘materials-by-design’ strategies to novel functional nanomaterials. To this end, she endeavors to exploit detailed understanding of structure-function relationships in the establishment of new, useful nanoscale architectures. Currently, she focuses on further developing a novel, robust all-inorganic (core)shell architecture for non-blinking semiconductor quantum dots. She is also working on a new approach to solution-phase synthesis of semiconductor nanowires that will permit complex heterostructuring at the nanoscale, as well as new approaches to assembling ordered arrays of solution-grown semiconductor nanowires. Finally, she is developing methods to assemble lanthanide ions and quantum dots to combine the interesting light-emission properties of each. Together, her applications interests include light-emission (optical tagging and solid-state lighting) and energy-harvesting (photovoltaics and thermoelectrics), and through collaborations, she is also exploring the human-health implications of nanomaterial manufacturing and use.
