She has developed her scientific career working in top academic institutions around the world, such as the Instituto Cajal (Spain), Washington University (US), Oxford University (UK), Turku Centre of Biotechnology (Finland) and the University of Chicago (US), among others. Her work was focused on the role of adult hippocampal neurogenesis, as a key mechanism in neuropsychiatric and neurodegenerative disorders.

*Scientific Achievements: Sylvia Ortega Martinez has established that the Neural Stem Cells responsible of Adult Hippocampal Neurogenesis are generated mainly in the postnatal day 6 (t.ly/3VPOw). This is a crucial discover in the field, as it explained the critical periods in postnatal stress that posteriorly have consequence in the adult life. Her second main achievement was to establish the role of the kinase JNK1 in neurogenesis and its implications in psychiatric disorders, such as stress, depression or anxiety. This discover was published in 2017 (t.ly/v9qn7). Finally, with her work at The University of Chicago, she has elucidated that microglia plays a crucial role in adult hippocampal neurogenesis, specifically in Alzheimer's disease conditions (t.ly/zP8DP). Currently Dr. Ortega-Martinez also implements courses and workshops in the Neuroscience field, being scientific divulgation one of her passions.

Craig Callan

Craig graduated from Farmingdale State University with a degree in Photo Technology in 1973.
From '73 to '78, he was a Photographic Quality Control Supervisor for Berkey Photo on the Lower East side of Manhattan. Among other responsibilities, he managed technical aspects of Kodachrome processing for slides and movie film.

In 1978, he started working for Colenta America Corporation, manufacturer of photo processing equipment. The company built both custom designed processors for clients such as National Geographic, Time/Life, Eastman Kodak, NASA, and the White House Photo Lab, as well as the more popular mini-labs. He specialized in solving complex photographic problems and in training operators to produce high quality images.
As part of Colenta's extensive export market he installed labs and trained operators in the Dominican Republic, Nigeria, and Jordan. He also designed factories and trained staff to assemble Colenta processors in Mexico and China.

As part of Colenta's growing cooperation with China, Craig was promoted to Communications Director in 1985. In order to surmount language difficulties, he used the desktop publishing software introduced for the Mac to create graphically centered manuals. As part of this, he used Digital Darkroom, the first retouching software available for the Mac. When Photoshop 1.0 was introduced in 1990, Craig was an eager early adopter.

When Craig moved to Washington, D.C. in 1991, he parlayed his desktop publishing and photography experience into a series of jobs with increasing responsibilities in the Graphic Arts Industry. One of the best was as a Mac Retoucher for Lanman Progressive, a high end "trade shop" which specialized in preparing color pages for major magazines and books. Once again, Nat Geo was one of his clients, and they supplied one of the most memorable instructions ever:

In November 1999, Craig was the Prepress Manager for a division of the Washington Post that printed 40 community newspapers, when he was asked to assume the role of Director of Technology and oversee the company's Y2K response. He remained in that position for the next five years, before taking a buyout and working as the Network Manager for a software company until retiring in 2019.

He maintains his interest in photography and Photoshop. He says "Teaching photographers about Photoshop is like teaching five year olds about ice cream. It's messy at first, but they soon get the hang of it."
Craig is looking forward to working on his personal development goals during retirement
• To improve his photography and Photoshop skills.
• To become a cantankerous old coot.

I started putting a concerted effort into capturing life around me in 2017, when I realized my kids were growing up entirely too quickly. Since then, I pretty much haven't stopped taking pictures - especially since starting my Project 365 in November of that year, which I'm now on year 5 of and still haven't missed a day!

As I have to imagine for most folks that take pictures every day, it's tough to be overly picky about your subject matter, and accordingly, I shoot most everything. A lot of around-the-house/town photography, candid family and pet images, remote flash experimentation, in-camera double exposures, and the occasional landscape excursion to mix things up &/or get out with friends.

I've joined PSA to improve my photography. I hope to grow from the feedback that I receive and provide through the monthly reviews and look forward to getting to know the folks I'm grouped with.

David Kepley

David Kepley

David's father was in the military, so he was raised in many different places, but went to high school on the north New Jersey shore. He went to college at Gettysburg College and graduate school at the University of Maryland. While working at the US Forest Service over 40 years ago, he was inspired by one of his colleagues to take up photography. A trip in which he visited some of the great parks in the American west cemented his lifelong love of trying to capture the beauty and majesty of the natural world. After his retirement, David has taken a number of different classes and workshops to perfect his craft. He is currently first vice president of the Vienna Photographic Society. His works have been juried into Nature Visions Photo Expo for the past four years, as well as the Joseph Miller Abstract Photography Exhibit. His work has also won many awards at his photo club. A passionate devotee of our national parks, during the 2016 centennial year David and his wife visited 10 different parks, capturing thousands of images of them! He hopes that the sense of awe and majesty that he sees in the natural world will inspire you as well.

Al first picked up a camera fifty years ago and has not put it down since.

Al is active with the Minnesota Valley Photo Club and regularly submits his photos to their monthly salons and displays his work in various venues supported by the club.
