JOANNA EDWARDS | DATA BASE TEAM
Joanna is project leader for the Excipients project, which currently involves 11 members sharing data on the toxicity of vehicles used in single and repeat dose studies. She has experience of in vivo and in vitro genotoxicity data entry and has peer reviewed genetic toxicity, hERG and skin sensitization records.
ANNE RIZET | DATA BASE TEAM
Anne-Laure, our newest database team member, is currently working on entering NIHS genotoxicity data and has a lot of past experience in environmental toxicity, particularly aquatic toxicology.
ANDREW THRESHER | DATA BASE TEAM
Andrew is leader of the Vitic 2010.1 data project and is responsible for all aspects of the data entered into the Vitic database. The key area of his work is skin sensitization and he has also worked on entering repeat-dose toxicity, genotoxicity and hepatotoxicity data records. Andrew carries out carcinogenicity and Excipients data peer review.
DAVID WILKINSON | DATA BASE TEAM
David is project leader for the Intermediates group, a data sharing initiative composed of 7 members sharing in vitro genotoxicity data. He also works on carcinogenicity and in vitro and in vivo genotoxicity data from a variety of sources. David also carries out peer review of skin sensitization and excipients data.
EMMA WILLIAMSON | DATA BASE TEAM
Emma is currently project leader of Vitic Nexus and is responsible for all aspects of the re-write. She has experience of data entry for genetic toxicity, carcinogenicity and repeat dose toxicity. She also carries out peer review of several endpoints including single and repeat dose data, reproductive toxicity, carcinogenicity and genotoxicity.
MOHAMMED ASHFAQ ALI | KNOWLEDGE BASE TEAM
Senior Scientist
Specialist Research Area: Meteor - Metabolism Prediction
Ash has written a number of biotransformations for Meteor versions 9-13. Much of this work involved varied and diverse chemistry, however recent attention has focused on implementing biotransformations that involve a specific bioactivation pathway.
Ash has made significant contributions to the development of rules pertaining to the metabolic pathways of heteroaromatic ring systems. Heteroaromatic structures are often used as bioisosteres in drug candidates and are therefore of great metabolic interest.
Other specialist areas of drug metabolism that Ash has contributed to include generating species specific reasoning rules and incorporating detailed enzyme information for existing biotransformations within the Meteor dictionary.
STEVEN CANIPA | KNOWLEDGE BASE TEAM
ALEX CAYLEY | KNOWLEDGE BASE TEAM
I joined Lhasa during the summer of 2007 to work on our Derek for Windows program. Initially did a small amount of work on a range of endpoints including, cardiotoxicity, neurotoxicity, skin sensitization and ocular toxicity. I then settled into writing alerts for the genotoxicity endpoints and it is in these endpoints which I have the greatest expertise.
I have written and updated numerous alerts for mutagenicity and more recently have been focusing on updating and increasing the number of alerts for chromosome damage within Derek for Windows.
LILIA FISK | KNOWLEDGE BASE TEAM
Knowledgebase scientist
I work on developing structure-activity alerts for Derek for Windows. My current area of research is in the diverse mechanisms of damage for the hepatotoxicity endpoint and I have developed alerts using data both from the published literature and donated data sets. One of my recent projects involved the identification of potential new chemical classes for hepatotoxicity, using Leadscope clustering software to analyse a FDA data set of compounds with human adverse drug reactions in the liver.
LAURA GIBSON | KNOWLEDGE BASE TEAM
Senior Scientist
Laura has worked on the Derek for Windows program since starting work at Lhasa in 2004. Since then she has worked on a number of endpoints, initially concentrating on the research and identification of structure-activity relationships for HERG channel inhibition and carcinogenicity. Her more recent work has focused on cardiotoxicity and teratogenicity, in addition to peer reviewing alerts for skin sensitisation and carcinogenicity.

ERNEST MURRAY | KNOWLEDGE BASE TEAM
The general metabolism topics that I cover include:- Biotransformation reaction mechanisms
- Reactive intermediates related to toxicological endpoints
- Structure Metabolism Relationships
- Plharmacokinetic aspects of drug metabolism
- Enzymes related to drug metabolism (P450, GST, UGT, hydrolases etc.)
MARTIN OTT | KNOWLEDGE BASE TEAM
MARTIN PAYNE | KNOWLEDGE BASE TEAM
Senior ScientistCurrently works primarily (as peer reviewer or researcher) on teratogenicity, skin sensitisation and aquatic toxicology (fish and invertebrates). In a Defra-LINK funded project he is currently contributing to an integrated testing strategy for skin sensitisation and aquatic toxicology and working on an extension of Derek for Windows to cover semi-quantitative prediction of the latter.
His experience extends to a wide variety of other endpoints including respiratory sensitisation, mutagenicity and carcinogenicity. His past experience has included skin absorption prediction and regulatory toxicology. He has a particular interest in the integration of mechanistic toxicology, pharmacokinetics and physical organic chemistry to practical structure-activity relationships.

MATTHEW WRIGHT | SOFTWARE DEVELOPMENT
I am a project leader at Lhasa for Derek API and Meteor. In this role I both oversee product delivery and work on the design and implementation of the applications. Most recently I have been collaborating with members and product management to capture requirements for the new Meteor Nexus rewrite, and have been working on the user interface design and managing its implementation.
I have 15 years commercial experience in Cheminformatics software, and have been involved in many of its aspects during that time; from code development through to product management and design. Prior to joining Lhasa I worked for a number of vendors such as MDL and IDBS on a variety of their product lines as well as doing bespoke consultancy projects. Before that, I studied for a Cheminformatics PhD with Peter Willett at Sheffield University on chemical structural shape similarity
