My Research Activities

My research is divided into four streams - 1) reaction dynamics, 2) atmospheric chemistry; 3) spectroscopy of radicals, and 4) science education. The first three are experimental research conducted in the Molecular Photonics Laboratories (co-led with Prof Tim Schmidt), while the third area is run in collaboration with researchers in the Advancing Science by Enhancing Learning in the Laboratory (ASELL)Project (www.asell.org)

1. Reaction Dynamics and Mechanisms

Collaborators: Prof Jordan (U.Syd.), Dr Osborn (Sandia Nat'l Labs), Prof Bowman (Emory Univ.) Prof Houston (Cornell Univ.) In this project we excite isolated molecules with a laser and detect the reaction products with exceptional sensitivity. In detecting the products we measure the speed of the fragments, their internal energy, and their orientation. This high level of detail allows us to determine the mechanism of the reaction, and to discover new mechanisms when known mechanisms do not fit the experimental picture. Our most significant recent discoveries include: i) Roaming pathways. Conventional chemical theory cannot explain many details of these reactions. ii) Phototautomerization. We discovered recently that when small carbonyls absorb light they undergo tautomerization. This might explain the origin of organic acids in the atmosphere, which is vastly underrepresented in atmospheric models.

2. Atmospheric Chemistry

Collaborators:  Prof Jordan (Univ. Sydney), A/Prof Fisher (Univ. Wollongong), Dr Hansen (UNSW), Dr Fittschen (Univ. Lille). In this project we discover new reaction mechanisms and pathways relevant to atmospheric chemistry.  Photochemical pathways are probed in the laboratory, validated using computational chemistry and tested in global atmospheric models.  We determine fundamental photochemical processes using molecular beam experiments, and also photooxidation and photo reduction fates of these fundamental processes under atmospheric conditions. Our philosophy is that atmospheric processes can only be truly understood if the fundamental process are first determined.

3. Spectroscopy of Radicals

Collaborators: Prof Schmidt (UNSW), Dr Osborn and Dr Taatjes (Sandia), Prof Heard and Dr Whalley (Univ. of Leeds) Free radicals are the chain carriers in almost all complex chemical reactions. Although they feature in chemical models, many have not been discovered. In this project we create and isolate free radicals using an electric discharge. The radicals are cooled in the molecular beam and subjected to spectroscopic and mass analysis, which allows us to determine the radicals that are formed. We are specifically looking for radicals that might be formed in the interstellar medium, radicals that are formed in engines, and radicals that are formed in the atmosphere.

4. Science Education

Collaborators: Prof Sharma (U. Syd.), Prof Buntine (Curtin Univ.) and other members of the ASELL team. Prof Buntine and I started the science education project called "Advancing Science by Enhancing Learning in the Laboratory" about 10 years ago. The project has 4 objectives: i) to create and share a database of good undergraduate science experiments; ii) to provide professional development for science academics in educational theory and practice; iii) to provide links and fora for academics to get together and discuss lab education; and iv) to conduct research into how students learn and engage in the undergraduate lab.

Areas of supervision

My area of expertise is in atmospheric chemistry, reaction dynamics and spectroscopy.  I can co-supervise projects in computational chemistry and atmospheric modelling.   

PhD scholarships are available for all projects listed below.  Please send me an email mentioning this page.

Projects that would be led by me:

New Atmospheric Mechanisms:  I am offering projects in the discovery of new atmospheric chemistry reaction pathways.  Atmospheric models are only as good as the underlying chemistry that they contain. Over the past few years we have discovered a number of new chemical pathways relevant to the atmosphere.  Photo-isomerization accounts for the production of organic acids that was previous under-estimated in models.  We discovered photo-thermal oxidation as a new chemical mechanism and are evaluating its role in the atmosphere.  This project is laboratory-based, using our state-of-the-art laser laboratory.

Reaction dynamics:  Chemical reaction dynamics is the study of fundamental reaction mechanisms.  The chemical "mechanism" refers to the specific motion of electrons and nuclei as a molecule proceeds from reactant to product(s).  Understanding of this mechanism allows prediction of the fate of an energised molecule and also the rate of reaction.  Over the past two decades, we have been pioneers in the investigation of "roaming" reactions. This project would involve the extension of our knowledge about roaming reactions into larger molecules, including acetone, and the development of knowledge about vector properties of roaming. This project is laboratory-based, using our state-of-the-art laser laboratory.

Molecular Spectroscopy:  The projects above all involve a detailed knowledge of molecular spectroscopy as the probe of chemical reactions.  This project involve the measurement and analysis of spectra that have never been measured before.  Target molecules are free radicals that are intermediates in complex chemical pathways, including radicals in atmospheric, combustion and astrophysical chemistry. This project is laboratory-based, using our state-of-the-art laser laboratory.

Projects that would be co-supervised by me:

Atmospheric fate of new refrigerants gases (project led by Dr Chris Hansen).  Hydrofluoroolefins (HFOs) are the new generation of refrigerant gases, replacing chlorofluorocarbon and hydrofluorocarbon gases that have now been banned by the Montreal Protocol and amendments.  This project will test a range of HFOs and their decomposition products in the atmosphere to determine whether these compounds are benign, or whether their use should also be regulated.

Computational chemistry or atmospheric processes (project led by Prof Meredith Jordan at U. Sydney).  Prof Jordan and I have collaborated for many years on atmospheric chemistry and reaction dynamics.  Computational chemistry is a crucial element of the interpretation of  laboratory results and confirms the discovery of new chemistry.  Computational chemistry can also predict the outcomes of new mechanisms that can be tested in the lab.  This project will be performed in conjunction with any of the three experimental project above.  The project is strongly computational in nature and can be conducted at either UNSW or U.Sydney.

Atmospheric Modelling (project led by A.Prof Jenny Fisher at U. Wollongong).  In support of the "New Atmospheric Mechanisms" and "New Refrigerants" experimental projects above, A/Prof Fisher collaborates with us to determine the consequences of our new chemistry discoveries in the atmosphere.  New discoveries in the lab are tested in extensive, global, atmospheric models.  In reverse, ideas about new chemical processes can be tested in models before exploring in the lab.  This project could be undertaken at either UNSW or UOW.
