I apologize for not posting any new announcements about CIOs over the past few days.\u00a0 CIO is in the process of deploying new blogging software, and I was instructed last Friday not to post anything new until my blog was moved over to a new server.\u00a0 I\u2019m back in action today, and I have many CIO announcements\u00a0to report.Yesterday, Dow Chemical announced that Dave Kepler\u00a0(pictured at left)\u00a0 was appointed senior vice president of the company.\u00a0 Kepler, who serves as head of shared services and CIO, will now also co-chair the Midland, Mich.-based company\u2019s environmental, health and safety board as well as chair its corporate environmental advisory council.\u00a0 In his new position, he will be responsible for driving Dow\u2019s sustainability and corporate security agendas.\u00a0 Kepler, who has served as Dow\u2019s CIO since 1998, takes on this new role from Larry Washington, who\u2019s retiring from Dow at the end of March.\u00a0 Kepler has worked for Dow since 1975. For more information on Kepler\u2019s new role, check out the press release Dow issued. Mark Gulling, a former CIO of Kodak, started his new job as packaging manufacturer MeadWestvaco\u2019s new president of global business services yesterday.\u00a0 Like Dow\u2019s Kepler, Gulling is responsible for his company\u2019s global internal services operations, which include shared services for HR, finance, logistics and IT.\u00a0 Two low-cost airlines announced new CIOs yesterday:Virgin America hired Bill Maguire as the Burlingame, Calif.-based start-up\u2019s new CIO. (The airline will begin flying as soon as it gets FAA approval.)\u00a0 Maguire, 52, doesn\u2019t appear to have any experience working for an airline.\u00a0 He most recently worked for Aspect Communications in San Jose as its SVP and CIO.\u00a0 Prior to that, he served as Legato Systems\u2019 CIO.\u00a0 He also previously worked for Amdahl and the U.S. Postal Service.\u00a0\u00a0 Scott Allard joined Spirit Airlines as its VP and CIO.\u00a0 He comes to the Fort Lauderdale, Fla.-based company from TravelWorm where he led the online travel agent\u2019s technology initiatives.Last week, Gary Wood started his new job as CIO of the Knights of Columbus, which is not just a location for Sweet 16 parties, but a $1.6 billion insurance company, which I never knew.\u00a0 Wood is based at the K of C\u2019s headquarters in New Haven, Conn.\u00a0 He most recently worked for NIIT Technologies as a senior management consultant where he was on a long-term assignment at Thrivent Financial for Lutherans.\u00a0 The executive search firm Horton International\u00a0placed Wood at the K of C.\u00a0 Steven Wallace has left his position as CIO of Constellation Brands, according to a colleague who tried getting in touch with him yesterday.\u00a0 I don\u2019t know the\u00a0f the circumstances in which he left the $4 billion spirits manufacturer and distributor. Last but not least: A friend of Jessica Denecour wrote to let me know that Denecour joined Varian Medical Systems as its VP and CIO.\u00a0 She most recently worked for Agilent Technologies as its VP of information technology solution services, and previously as Agilent\u2019s VP of information technology infrastructure services.\u00a0 This friend says Denecour is \u201ctop notch.\u201d\u00a0 Apparently Varian Medical Systems thinks so, too.
