Biographical Details

Junming is a graduate of the University of Western Australia (B.Sc.) and the Australian National University (B.Sc. (Hons) and PhD). He was the receipient of the Lady James Prize for Physical Science (UWA), University Medal (ANU), Director's Prize (ANU) and Cornforth Medal (RACI). After obtaining his PhD under the mentorship of Prof Michelle Coote and Prof Christopher Easton at the ANU, he moved to Yale as an A*STAR International Fellow. Since mid-2015, he was a research scientist in the Institute of High Performance Computing in Singapore before commencing his current position in UNSW. In 2017, he was awarded an ARC Discovery Early Career Researcher Award. 

Research Interests

We develop and apply computational methods to help design and develop new catalysts and drug molecules. Topics of particular interest include, but are not limited to organocatalysis, reactivity on surfaces, machine learning in chemistry and modelling solvent effects. Examples of current projects:

  • Large-scale prediction of pKas of organocatalysts and drug molecules
  • Computer-aided design of new catalysts and anion receptors
  • Hybrid quantum mechanics/molecular mechanics simulations of solvation and surface dynamics
  • Developing linear-scaling ab initio composite methods for quantum thermochemistry and kinetics

Opportunities

5 August 2017: Two PhD scholarships (international or local) available to start in 2018. Interested students are encouraged to send me a CV with contact details of 2 referees. Informal enquiries about potential projects are also welcomed. 

Projects can generally be tailored to suit the interest and background of students. We work closely with experimental groups so there would be opportunities for students to gain expertise in both computational and experimental research. Undergraduate, Honours, PhD students and visiting fellows are encouraged to get in touch with me to discuss potential projects and funding opportunities. For most projects, no background in computational chemistry is assumed, and training will be provided.
