I was part of the group that made it possible for Chris Reeve to have sensation in over 80% of his body and able to go without his ventilator for long periods of time. I think that is pretty big stuff. I spent a day with Alan Alda while he did one of his American Scientific Frontier shows focusing on our lab too. I now have quit working due to having Fibromyalgia and have become a full time quilter!!! What a change, huh? I see Sue often at the quilt stuff. I have moved back to my hometown of Salem, IL. My husband lives in China with his job, at least 2 more years, so I came back home. The house I grew up in was for sale so I bought it and here I am. I love being around family again even though they are a pain much of  the time.

  65. Amber McGee, B.S. Biology 2000. Amber did a study of humic acids in Schulz Bog near Rhinelander Wisconsin. She found that there was a lot more humic acid in the sediment core when there were also lots of Sphagnum spores.
  66. Maggie Coad. B.S. Biology 2000. Maggie did some preliminary pollen analysis of a core from Horseshoe Lake, Alexander County, Illinois. Her work showed that Taxodium pollen became abundant in the sediment core when European-American Pioneers colonized the site. The current lovely cypress forest in the lake did not exist before pioneer farmers arrived around 1815.
  67. Lynne Malone  2001.  Lynne did pollen analysis of  woodland hollows in the Upper Peninsula of Michigan.  She is continuing that work as a graduate student.
  68. Mona Callis MS Biology  2001 Mona  did a  pollen analysis of a core from Schulz Bog near Rhinelander, Wisconsin. The bog is located well away from the Upper Peninsula and the lake-effects snows of Lake Superior. Bog development there was very similar to other sites in the Upper Peninsula indicating that there is little impact of lake effects snows on bog development. 
  69. Michelle Crenshaw  MS Biology 2001 Michelle did a thesis on the Paleolimnology of Horseshoe Lake in Alexander County, Illinois.  She showed that the lake was very different in pre-settlement times.  Her diatom analysis showed that the lake was shallow with lots of aquatic macrophytes.  The modern diatoms show a very eutrophic lake.  Michelle is now at the University of Waterloo in Canada working on her Ph.D. with Roland Hall.
  70. Chad Rieger MS  Environmental Sciences 2002.  Chad’s thesis was a phosphorus budget for Cougar (formerly Tower) Lake on the SIUE campus.  He found that the lake is losing far more phosphorus than in coming in through the campus sewage treatment plant.  The plant currently uses tertiary treatment to remove phosphorus.  We think the lake is still losing phosphorus that was deposited in the sediment before the plant came on line.  Chad has moved on and is working as an environmental scientist for the State of Montana The title of Chad’s thesis is “A Phosphorus Budget for Cougar Lake in Madison County, Illinois”.
  71. Sashi Vissa MS Environmental Sciences 2002.  Sashi is from Hyderabad in India.  Her thesis was on the effects of  cadmium and zinc on growth of Loblolly Pine (Pinus taeda). She started her thesis work under Jim Houpis, but he left for another university.  Sashi is employed by an environmental consulting firm in Rockville, MD.   Her thesis title is: “Applicability of Pinus taeda in Phytoremediation of Cadmium and Zinc Contaminated Soils”.
  72. Erin Hammer BS Biology 2002.  Erin’s senior project was a study of  spheroidal carbonaceous particles in Horseshoe Lake, Madison County, IL.  She was a pioneer for our lab.  She developed the technique and showed that it was feasible.  We will be continuing with her work.
  73. Jennifer Martin, Biology.  Jennifer completed a study of  pollen in a short core from Horseshoe Lake, Madison County, IL.  Her work showed the location of the culture horizon.
  74. Adam Hayes. BS Biology 2002.  Adam did a study of Cougar Lake inorganic carbon.
  75. Brian Vermillion.  MS ENSC 2003.  Brian did a study of  sediment chemistry at Horseshoe Lake, Madison, County, Illinois.  He found that Pb, Zn and Cd increased in starting in the early 1900’s.  He concluded that these elements entered the lake from a Pb smelter located in the adjacent town.  The title of  Brian’s thesis is  “Major Element and Heavy Metal Concentrations in Horseshoe Lake, Madison Co., IL”.  Brian is continuing on to the Ph.D. program in Environmental Sciences at the University of Illinois.  He will be studying phosphorus in Illinois streams.
  76.  Indu Bala MS ENSC 2003.  Indu also worked with Dr. William Retzlaff.  She did a study of stable isotopes of  nitrogen in Horseshoe Lake sediment.
  77. Micah Miranda. BS Biology 2003.  Micah did a study of Cougar Lake temperature profiles.  He placed a series of Onset HOBO temperature loggers at depth intervals in the lake.  His purpose was to study the impact of the University’s heated water effluent on lake stratification and temperature budget.
  78. Kevin McKaye.  BS Biology 2004.  Kevin continued Erin Hammer’s study of  carbonaceous particles in Horseshoe Lake sediment.  He found that it is possible to measure carbon black using the same equipment used to measure stable isotopes of carbon.  His approach could greatly simplify the measurement of elemental carbon in lake sediment.
  79. Christina Blackford B.S. Biology 2005.  Christina did a senior assignment project on stable isotopes in sediment from Sylvania Wilderness lakes and hollows.  She found that δ15N values decreased in up core in High Lake.  Her results indicate that nitrogen from air pollution reaches this lake in a Wilderness area.
  80. Dave Novak M.S. Biology 2005.  Dave completed a study of the heat budget of Cougar lake that Micah Miranda started.  Dave used HOBO data loggers to record the temperature of the lake water at 2 hour intervals for 2 years.  He showed that the SIUE heating and airconditioning plant contributes only small amounts of heat to the lake.  The title of  Dave’s thesis is “Heat Budget of Cougar Lake, Madison County, Illinois”.  Click for a pdf of Dave’s thesis.
  81. Shelly Ottensmeier MS ENSC 2005.  Shelly completed a study of stable isotopes of  seston in Cougar Lake.  She found that δ15N  increased over the summer as a result of  sewage inputs from the campus.  Dr. Retzlaff was co-advisor.  Shelly works in TekLab, a local environmental firm.  Click for a pdf of Shelly’s thesis.

  85. Nick Grant BS BIOL 2006:  Nick came to SIUE with a strong interest in aquatic entomology.  He did a study of benthic invertebrates in Cougar Lake.  He found a strong decline in diversity in samples taken from the anaerobic hypolimnion of the lake. His results were similar to other eutrophic lakes like Linsley Pond, CT and Lake Mendota, WI. Nick is currently employed by the U.S. Bureau of  Mines inspecting surface coal mines in Illinois. Click for a pdf of Nick’s final presentation in the Ecology Evolution and Environment Colloquium.

  87. Brandon James BS BIOL 2006.  Brandon did his senior assignment project on the “200 lb squirrel project”. Our collaborator was Dr. Marian Smith from the SIUE Biology department.  We planted seeds of various species of Illinois oaks and walnuts around the SIUE campus.  Each seed was marked with a numbered flag.  Our purpose was to test Bazzaz’s hypothesis that reforestation in Illinois is limited by the ability of large seeded species to disperse to open sites.  Brandon examined field and laboratory germination and survival rates using the tetrazolium method.  Brandon presented his work at the 2006 Illinois State Academy of Sciences Meeting in Chicago.  Click for a copy of his ISAS poster (pdf).  Brandon is a Ph.D. student in plant physiology at the University of Illinois Champaign.
  88. Beth Martin BS BIOL 2007.  Beth did her Ecology Colloquium talk on nitrate in Cougar Lake.  Her question was whether denitrification in deep eutrophic lakes removes nitrate from water.  She took weekly samples at meter depth intervals from the lake and analysed them for nitrate using a nitrate electrode.  Click for handouts of her talk (pdf).  Beth is continuing with her studies in the SIUE Biology MS program.  
  89. Phil Williams BS BIOL.  Phil completed his senior assignment project in the lab.  He did a study of stable isotopes in the sediment of Cougar Lake.  He found that the recent invasion of the lake by Myriophyllum  increased the δ13C value of shallow water sediment.  Live Myriophyllum  showed elevated 13C levels because the large beds of macrophytes are extremely carbon-limited.  A portion of the carbon fixed by the macrophytes is incorporated into the lake sediment.  Phil presented his results at the Illinois State Academy of Sciences meeting in Springfield.  Click for a copy of his poster (pdf)
