Research interests:

I first joined the Paleolab while pursuing my undergraduate degree from Florida Tech in 2012. As an undergraduate, I was trained in diatom identification, reconstructing past limnological conditions, and macrocharcoal analysis, reconstructing past fire regimes. This training was applied to my undergraduate research tracing lake level fluctuations and climatic conditions during the last interglacial-glacial transition in Panama (See Shadik et al, 2017). The experience I gained as an undergraduate inspired me to continue paleoecological research as a graduate student. I graduated in May of 2015 from Florida Institute of Technology with a Bachelors degree in Marine Biology, and I began as a PhD student in the Paleolab in Fall 2015. 

My present research has shifted geographically from Panama to the Peruvian and Ecuadorean Andes, as well as temporally from glacial-interglacial transitions, to the Holocene. As a PhD. Candidate, I am investigating the influence of Mid-Holocene climate on the rise of Andean camelid pastoralism.  My study area streches from Ecuador, down to southern Peru using the dung fungus Sporormiella as an indicator for domesticated livestock. I will also evaluate the cascading effects of camelid domestication including landscape disturbance and quinoa domestication. 

Teaching Experience

Since beginning my PhD, I have been a teaching assisstant within the Biology Department (now the department of Ocean Engineering and Marine Sciences). An overview of each teaching position is below.

General Ecology Teaching Assistant: Laboratory Instruction including experimental design and univariate statistics in a 3000 level course. Fall 2015 TA.

General Biology Teaching Assisstant: Two Fall semesters of laboratory instruction for introductory Biology. Modules were focused on using laboratory equipment and introduction to genetic transformation. Fall 2016, Fall 2017 TA. I have also been involved with a study to evaluate the influence and efficiency of online laboratory notebooks vs hard copy lab notebooks (stay tuned!).

GIS Teaching Assistant: Laboratory Instruction of GIS using ArcMap and student troubleshooting. As of Spring 2018, duties include class design and lecturing as well as laboratory design and lab instruction. Taught in the Spring semester. Spring 2016, Spring 2017, Spring 2018, current TA. Please feel free to contact me if any GIS work or help is needed. 

 Field Experience

Summer 2015: Field work in the Junin region of Peru collecting limnological data of small lakes surrounding Junin. Activities included: Bathymetry data collection, surface sediment collection with an Ekman dredge

Summer 2017: Coring expedition in northern Peru at Lakes Huayabamba and Progreso. Activities included: Piston coring, universal coring, bathymetry, plankton tows, sediment collection and preservation. Transfer to Ecuador to take bathymetry of lake Rodeococha in Llanganates National Park.

Summer 2018: Coring expedition in northern Peru at Lake Changali. Activities included: Universal coring, plankton tows, bathymetry, sediment collection and preservation.
