Bio

JGP as pool shark, taken by my niece Pamela, October, 2009, using a Canon 5D Mark II with Pentax Super Takumar 50mm f1.4 lens and the Vemar cross filter that came with it. If only I were a shark! (My brother Bill still beats me on a regular basis).

JGP on Rush Creek, East Texas, 2007, while doing botanical research.

JGP was raised in northwestern Louisiana, in the small town of Plain Dealing, Bossier Parish, which forms part of the region called the Ark-La-Tex. His early life was filled with fun experiences in the pine forests of the rolling hills and in the farm lands of the Red River Valley. His interest in science was a natural, but took a little "discovery." When he took a freshman geology class in college, he reacted with consternation: "Why didn't somebody tell me all this stuff!" He has degrees from Centenary College of Louisiana, Southern Methodist University, and the University of Texas. He has taught at Centenary College of Louisiana, Lamar University, Texas A&M Commerce, and the Univ. of Colorado at Denver.

Research Interests

Biology

This is a new direction for me. "Modern" human-caused problems have been on my mind for years, and certainly have been the focus when teaching Environmental Geography and Geology. It became evident to me that I might be effective at working on these problems, starting with the knowledge I have about the evolution and diversity of Life, and about such things as computer mapping and sedimentary geology, if knowledge about biology, especially field biology, is added to the mix. So, I took biology courses at Lamar from 2005-2008, enjoying them immensely and learning much about plants, animals, and ecology. During that period I hiked the units of the Big Thicket, and became especially familiar with the new northern units along the Neches River south of Town Bluff, and the lands to the west along Rush Creek.

Computer Programming and Mapping

I learned to program in C and C++ when working for a computer mapping company during graduate school, having had a little coursework in school (PL/1 and Fortran). That work involved writing software to help geologists map underground rock layers in the effort to find oil and gas deposits, mineral deposits, and water resources. After graduating and beginning my academic career, C and C+ were replaced by Java for programming efforts. Most recently programming work has extended to Python, especially for data manipulation and production of illustrations. For several years I've focused Internet work on Zope and Plone, which are web software systems, both written in Python. In 2009 I plodded my way into Objective-C and PyObjC for Mac OS X programming, and am hoping for a flurry on that front!

Stratigraphy

Much of my academic research has involved the study of sedimentary rock layers and their correlation using well logs, surface data, and fossils. One project, an offshoot of Master's thesis research, concentrated on mapping underground layers of anhydrite (similar to gypsum) in Texas, Louisiana, Arkansas, and Mississippi. Another involved the description of the Glen Rose Formation on outcrop across the central part of Texas, into Oklahoma and Arkansas. The distribution of dinosaur footprints on layers within the Glen Rose Formation and adjacent rock units was a big part of my dissertation, from which several research projects continued. Recent teaching in 2009 has revitalized an appreciation for knowledge of local geology.

Paleontology

Most of my paleontological work has involved dinosaurs and other vertebrate animals. I have worked on significant excavations of hadrosaur bones from Upper Cretaceous rocks in Chihuahua, Mexico and of sauropod bones from Lower Cretaceous sandstone southwest of Fort Worth. I have also studied fossils from the Cretaceous of southwestern Arkansas, and from the Cretaceous of Colorado. Most recently, collections were made of Cretaceous shark and fish teeth from Arkansas. Several computer programming projects target several items for biology and paleontology, notably PhylogeneticTree.

Vertebrate Ichnology

I started studying dinosaur footprints during Master's thesis research in Arkansas, when I found thousands of sauropod dinosaur ("brontosaur") footprints on limestone layers in an active gypsum quarry. Work on fossil footprints became a specialty, and in addition to Texas and adjacent states, this research has taken me across the American West, especially Colorado and Utah, and Mexico. In Mexico I worked as far south as Puebla, south of Mexico City. Most of this ichnological research has concerned the footprints of dinosaurs, but I have also investigated Permian fossil footprints from West Texas, made by pre-dinosaur age land animals.

Personal Interests

Photography

Photography has been an important part of scientific work, and bird and Nature photography, and I've had fun taking photos of my nieces and nephews, and now grand-nieces and grand-nephews. My first camera in the early 1980s was a Nikon FE2, with a 50mm f1.8 lens. I remember the big deal a few years later, adding a Nikon F3HP camera, 135mm f2.8, 55mm macro f2.8 with PK13 extension tube, and two Kiron zooms, a 28-85mm and an 80-200mm. I used the Kiron 28-85mm zoom for years and years on the F3, because it was so handy to photograph dinosaur footprints right at my feet, dinosaur trackways, and local setting shots. For aerial photography of dinosaur footprints in Arkansas, a local cropduster pilot took the doors off a Cessna Aerobat, which allowed me to shoot nice aerial photographs, using the Kiron zoom at 28mm and the motor drive on the F3HP firing (It was cold that morning!). The 135mm f2.8 lens was great for portraits (still is!), and has been a favorite lens. For a while there I was doing regular work in the darkroom on black and white photography, doing many prints for my dissertation work. With the advent of digital photography, I started out with the feeble offerings of point-and-shoot, but really enjoyed the Nikon Coolpix series when it moved through. I had the Coolpixes 950, 990, 4500, and P5000, and used them mainly for digiscoping, using a Leica APO Televid 77 spotting scope (broke the first one in half, but replaced it). My first DSLR was the Nikon D200, which I got with the handy 18-200mm zoom. I have used the D200 for natural history work and for family photography. For a while the D200 was fitted with a GPS, but I learned to also use timecodes and Python programming to sync with GPS data recorded separately. Most recently (2009), I took the plunge on a Canon 5D Mark II camera, and adapted the Nikon lenses. The 5D Mark II shoots great stills as well as video, which really got my attention. I shopped for Nikon manual prime lenses and zooms, and a few manual Minolta and Pentax primes. These go with much equipment to make a tripod and handheld video system. To get started, I "engineered" the better part of shoulder mount and hand-held kits for video, by using pieces-parts from digiscoping rigs, ACE hardware and hobby shop finds, a few bits bought online, and a basic tap-and-die set, augmented by my brother Bob's shop equipment. On the computer software side of video, I've been learning to edit stills and videos using Aperture, Final Cut Pro and related software. Set up for video digiscoping also.

Audio

In the early 2000s, I discovered the NatureRecordists Yahoo discussion list (via the DigiscopingBirds discussion list), and got the Nature recording bug. For a year I made weekly visits to seven specific spots on land along the Neches River, land that was to become a new unit in the Big Thicket National Preserve. I used a Sony minidisc recorder and a Sennheiser ME67 long shotgun microphone to record for about 15 minutes at each of the seven locations each morning, staring before the crack of dawn and ending mid-morning, and learned bird and frog calls (How easy it is to forget them! Drat!), amassing much recorded audio I have yet to process properly, a typical fate. I've used the same rig here and there to get wonderful audio of birds and natural sounds. More recently I added a newer Sony minidisc recorder, and record directly to the Canon 5D Mark II through a preamp. I still use the Sennheiser ME67, but added a matched pair of Rode NTA-1 low-noise microphones for stereo recording. Nature recording can be a humbling and depressing experience, with so much human-caused noise pollution, but recording great audio in remaining natural areas helps inspire us to conserve.

JGP (far right) lead a group of students on the Hermit Trail into the Grand Canyon in May 2003. This photograph was taken after the all-day hike up from the bottom - you can see a little wear on us :) Hiking the Hermit Trail is a challenge, but is something you don't forget, not just for the spectacular scenery and geology, but for the sense of accomplishment.

The Grand Canyon hike was a special experience. Here we pause for a break along the Hermit Trail, taking in the awe-inspiring vistas.

JGP has been expanding his horizons toward biology. Here he (far right) is pictured with Dr. Mike Haiduk (far left) and Lamar biology students at the highpoint of their hike up Stair Mountain in Black Gap Wildlife Management Area, during Dr. Haiduk's January, 2004 biology field course entitled Desert Field Mammalogy
