Claire Fraser-Liggett, Mark Gessler, Sue Siegel, Robert Wayman, Daniel Geffken

Claire Fraser-Liggett has resigned as president of the Institute for Genomic Research, In Sequence’s sister publication GenomeWeb Daily News reported this week.
Fraser-Liggett will leave TIGR on April 20. It was not immediately clear who will take her place at TIGR, which is a division of the J. Craig Venter Institute.
News of Fraser-Liggett’s departure was disclosed in an e-mail sent to JCVI colleagues by Craig Venter, JCVI president and CEO, which said she will leave “to pursue a new position.”
Fraser-Liggett, who is Venter’s former wife, has been TIGR president and director since September 1998. Her decision to resign comes five months after TIGR and the J. Craig Venter Science Foundation consolidated under the JCVI in early October.
Following the consolidation, Venter became president and chief executive officer of JCVI. Fraser-Liggett remained as president of TIGR, which became a division of the JCVI.
The integration of TIGR, TCAG and the JCVI came two years after Venter consolidated what at the time were four independent non-profit organizations — the J. Craig Venter Science Foundation, the Institute for Biological Energy Alternatives, TCAG, and the foundation's Joint Technology Center — into the J. Craig Venter Institute.

Mark Gessler has stepped down as CEO of Gene Logic. The company’s board of directors elected Charles Dimmler to replace Gessler as president and CEO. Dimmler has worked for more than 20 years in life sciences financing and has served as a director of Gene Logic since 1996.
Gessler will remain on Gene Logic’s board of directors.

Sue Siegel has resigned her post as president emeritus of Affymetrix, the company said in a Securities and Exchange Commission filing last week.
Affymetrix has not disclosed the reason for Siegel’s resignation or said who will replace her as president emeritus.
Siegel joined the company in 1998 as vice president of sales and marketing, and was named president and appointed to the company’s board within two years.
Separately, Affymetrix announced last week that it has named Robert Wayman to its board of directors.
Wayman recently retired as executive vice president and CFO at Hewlett-Packard. He had also been a director at HP, Conway, and Sybase.

Codon Devices has appointed Daniel Geffken to the post of chief financial officer.
Geffken most recently was executive vice president and CFO at Konarka Technologies.
He has also served as CFO and held positions involving fundraising, investor relations, and management at Transkaryotic Therapies, CytoTherapeutics, and Omnisonics Medical Technologies.
