About us

Our passion is pushing boundaries with original ideas, adapting to the ever changing scientific and technological landscape.

Our story

Where we came from

Keymodule was founded in 2005 by Professor Peter Johnson to further develop software solutions arising from his University of Leeds research projects. His interest in software solutions for difficult chemistry problems had been triggered many decades ago by a stay in Nobel laureate E.J. Corey’s lab at Harvard University, where he worked on the LHASA project for synthesis planning. After joining the Chemistry department at the University of Leeds his research was split between organic synthesis and software solutions for a variety of problems in chemistry. 

Where we are heading

Peter’s vision has inspired us at Keymodule to turn his ideas into high-performing, easy-to-use, versatile software solutions. We are particularly proud of our flagship solution, CLiDE, which was a trendsetter in chemical OCR and has now become the leading tool in the industry.

Our passion is pushing boundaries with original ideas, adapting to the ever changing scientific and technological landscape, and collaborating with our clients to meet their own individual needs and accelerate their breakthroughs. Because a win for you is a win for us.

Who we are

Prof. Peter Johnson

Managing Director and Scientific Advisor

Peter Johnson joined the University of Leeds in 1980, and led two thriving research groups, one concerned with the development of new synthetic methods and the total synthesis of natural products. Highlights of the latter include a particularly effective synthesis of the unusual terpene B-Vetivone, and the first synthesis of the complex alkaloid, gelsemine. In addition, he participated in a variety of multidisciplinary projects aimed at antimicrobial and antimalarial drug discovery, with emphasis on protein structure based drug design.

Work in computational chemistry started with a collaboration with the Harvard group on the further development of the LHASA program for synthesis planning, and then branched out to a variety of completely different projects concerned with tools to aid early stage drug discovery, including tools for protein structure based hit discovery and optimization, synthetic accessibility and extraction of structural information from the chemical literature. The final University project was developed as part of the EU funded CHEM21 project concerned with the discovery of new green chemical processes for drug manufacture and resulted in the CHEM21 ELN, a new electronic notebook, designed to record in detail the experiments conducted by the experimental scientists in the consortium. The many outstanding co-workers in these projects have gone on to establish themselves as world leading chemoinformatics experts in various academic and industrial settings.

Peter was also a founding member of a number of companies who developed their own software solutions. These include LHASA Ltd, a not for profit company founded in 1983, which has since developed into the world leading provider of toxicity prediction software and now has more than 180 employees, ORAC (reaction storage and retrieval and the first to make use of reaction mapping), SYNOPSYS (chemistry spreadsheets), and SIMBIOSYS (eHiTS docking software and ARChem for synthesis planning, the latter now providing the foundation for the CAS retrosynthetic analysis system.

Aniko Valko, Ph.D.

Chief Technical Officer

Aniko leads our development team with a focus on quality, functionality and production. She manages our flagship product, CLiDE, and actively works on it as a developer. She knows CLiDE inside out and keeps pushing CLiDE to the next levels by coming up with exciting algorithms and software designs, whilst maintaining a high standard in their implementation. 

In her free time, she enjoys spending time with her family and friends, and following a healthy and active life style.

Anthony Cook, Ph.D.

Chief Software Engineer

Tony began his career in chemo-informatics in 1983 when he joined Peter’s group at the University of Leeds to help develop a novel computerised reaction retrieval system. Subsequently, he worked at ORAC Ltd developing the reaction retrieval system into a successful commercial product. He was a founder of Synopsys Scientific Systems, a company focused on integrating chemo-informatics tools into popular desktop applications. After a stint working for BCI Ltd as a consultant, he co-founded Digital Chemistry, a company focused on developing tools to efficiently search chemical patent databases. In 2010 he returned to the University of Leeds to conduct research into advanced algorithms for the treatment of stereochemistry in computer aided organic synthesis. After gaining a PhD he has worked on the EU funded CHEM21 project, then as a consultant for Wiley and the Chemical Abstracts Service helping with the integration of stereo chemical functionality into synthesis planning applications. He has now joined Keymodule Ltd to assist in the continuing development of CLiDE.
