Research:
 
One of the great quandaries of our age is that despite all our scientific progress, our attempts to improve human lives often seems high-risk, time-intensive and expensive.  The genetic code has been deciphered, thousands of genomes have been sequenced, and most protein folds are now known. However, our understanding of how dynamic organelles and living cells are formed is at its infancy, and more effective drug molecules for addressing the unmet needs of patients are ever-more costly to design and deliver.
 
To address the gaps, we focus on three areas:
 
  1. To move from the genetic code to cellular organization, we are determining how proteins recognize lipids and reshape membranes.  Our successes include the elucidation of how FYVE and PX domains bind the phosphoinositol 3-phosphate lipids found on endosomes, and how PH domains recognize phosphoinositol 4-phosphate on Golgi membranes. Working with collaborators we also discovered how the Bro1 domain recruits proteins to late endosomes, and developed predictive “MODA” software for identifying novel membrane binding surfaces on virtually any protein structure. Ultimately we hope to decipher the phospholipid code whereby proteins recognize complex membrane surfaces and shape dynamic organelle structures.

  2. To understand disease mechanisms we study oncogene products, critical pathways used by viral and bacterial pathogens, and proteins exhibiting mutations that correlate with debilitating human disease. Our targets include GTPases, kinases and phosphatases and their regulatory domains, tetraspanins including the CD81 receptor for Hepatitis C virus, and desmosomal proteins that mediate cell adhesion and cytoskeletal attachment.  By elucidating the structures, dynamics and interactions of these systems, we hope to expose new opportunities for therapeutic intervention.

  3. To reduce the cost of drug discovery and open up entirely new target areas, we are developing tools for the research community.  Libraries of molecules including biological signals and drug fragments have been assembled to identify novel pockets and starting points for efficient lead discovery.  Biophysical methods including nuclear magnetic resonance spectroscopy are being harnessed to identify hits and binding modes.  Polymers are being used to solubilize and study challenging membrane protein targets.  These tools are shared freely on-line, via open access facilities like NANUC, and through collaborative projects where further development is needed.
 
Our lab’s ethos is team-based and collaborative, and involves international consortia and funding from across the world. We partner with industry to address global challenges including tackling novel targets and cancers lacking effective cures, we work with business to develop new products, and engage with leaders to inform policy and spur innovation.  
 
Please let me know if you would like to work with us, I am particularly looking for motivated students, talented postdoctoral fellows, research collaborators and commercial partners.
