Dwayne Heard's Group

Atmospheric Chemistry and Astrochemistry

Welcome to my group's webpages. In these pages you will find out more about the laser-based field instruments we have developed for the atmospheric measurement of OH, HO2, RO2, and other free-radicals, OH reactivity and carbonyl species. We have deployed our instruments in over 25 field campaigns worldwide since 1996 from ground, ship- and aircraft-based platforms. You can also find out more about our studies of chemical kinetics and photochemistry performed in the laboratory which are relevant to Earth's atmosphere and also very cold regions in the interstellar medium. You can also access the publications from the group.

You can also find out who is in the group, and what opportunities there are for postgraduate studentships and postdoctoral fellowships.

Please use the links on the left hand side of the page to navigate.

I hope you enjoy reading our webpages. If you have any queries, please do not hesitate to contact either myself or one of my group, who will be more than happy to help you.

PhD Opportunities

Postdoctoral Fellowships



Nature Paper

Congratulations to Jack (Chunxiang) Ye, our newest group member, who is first author on a Nature paper which was published this week, and which describes a newly discovered source of HONO and NO2 from the photolysis of particulate nitrate.

INFAMOS grant awarded by NERC

3rd March 2015. A new project has been funded, led by Leeds and also involving collaborators from Oxford University, in which new optical spectroscopic methods will be developed for direct speciated detection of HO2 and CH3O2 radicals in the atmosphere.

Congratulations to Pascale

15th August 2014.   Congratulations to Pascale who this week not only submitted her PhD thesis, but also accepted a postdoctoral position at the Max Planck Insitute for Chemistry in Mainz, Germany, where she will be working in the aerosol group with Manabu Shiraiwa

Cape Verde Blog

24th June 2014. Hannah and Trevor are currently on fieldwork in Cape Verde as part of the ORC3 campaign, which is a collaboration between the Universities of Leeds and York. An instrument based on laser-induced phosphorescence is deployed to measure glyoxal. Hannah is writing a blog on her experiences. Picture: 1

Instruments at York

5th June 2014. The field campaign at York is underway, with several FAGE instruments operating to measure OH, HO2, RO2, OH reactivity and formaldehyde. Instruments are also operating in collaboration with the Universities of York and Birmingham to measure a detailed suite of VOCs, nitrous acid, missing OH reactivity and other supporting measurements including O3/NOx/CO.

FAGE leaves for fieldwork

2nd May 2014. The FAGE container leaves for fieldwork at the University of York, as part of a project to identify missing OH reactivity in the atmosphere. Pictures: 1 2

Poster Prize

1st May 2014. Congratulations to Rebecca for winning a Skinner poster prize at the recent Faraday Discussion 168  on "Astrochemistry of dust, ice and gas" which was held at Leiden in the Netherlands  7-9 April 2014. The title of her poster was "Chemical mechanisms operating at very low temperatures to enhance the rates of gas phase reactions relevant to interstellar environments".
