Research

Research Interests

1. Mechanisms underlying synaptic and behavioural plasticity that contribute to drug and alcohol dependence and abuse.

2. Consequences of alcohol abuse on brain function and its consequences for cognition and emotion.

3. Psychopharmacology, especially of benzodiazepines and excitatory amino acid antagonists with regard to their anxiolytic and cognitive effects.

4. Studies of learning and memory in genetically manipulated animals. 

5. Genetic contributions to drug abuse and addiction using mouse models, including studies of impulsivity in mice.

 

Research Support

My research has been consistently supported by the UK Medical Research Council.

I am PI on current MRC grants studying:

  • the consequences of multiple detoxifications from alcohol abuse on brain cognitive and emotional function

and

  • the role of GABA-A alpha2 receptor subtypes in cocaine abuse.  

I am PI of the MRC cross-institutional Addiction Research Cluster  "GABA" .

Within the Cluster, I am PI on the recently awarded grant 

  •  GABA-A receptors in accumbens neural circuits underlying drug abuse: novel targets for treatment.

My work on the genetics of impulsivity and drug abuse is supported by the EU FP6 Programme, under the umbrella IMAGEN

I am a co-investigator on an  EU InterReg grant "ALCOBINGE", that studies the short and long term effects of alcohol bingeing on health.

My own contribution is on the consequences of alcohol abuse for impulsivity.

ALCOBINGE is a collaboration between the Â鶹´«Ã½ of Sussex and the Universities of Rouen and Amiens.

Doctoral work in my lab is currently supported by doctoral training awards from the MRC and BBSRC.
