Martina Calovi

I’m a Postdoctoral Scholar since January 2018. I first visited GEOLab during fall semester 2016 to complete my Ph.D. dissertation on the use of GIS tools for emergency management. I obtained my Ph.D. in Change and Complexity Management, in December 2017, at Sant’Anna School of Advanced Studies in Pisa, Italy. My dissertation focuses on bridging geography with healthcare and disaster management. Particular attention was addressed to the use of GIS to support the spatial reorganization of outpatient care services delivery and to understand how much the proximity affects the patient’s choice of specialized cardiological visit in Italy. The third part focused on the development of, a dynamic downscaling of Global Forecast System (GFS) forecasts using Personal Weather Stations, during extreme heat events. The methodology has been developed and tested over the Manhattan borough. The overall main goal was to analyze the accessibility to health care services and first aid facilities, in regular conditions and during emergency situations, focusing to the needs of the most vulnerable population.

My research interests cover Geographical Information Science applied to natural disaster and emergencies, climate change, extreme weather events forecast, data fusion, interactions and coexistence between human and physical environment, and the managerial implications of geographical analyses into the decision-making process.

Ph.D. Graduate Students

Laura Clemente-Harding, M.S.

I am a Ph.D. student in the Department of Geography. I completed my Bachelors degree in Meteorology with an Environmental Inquiries minor in 2007 at Penn State. In 2009, I graduated from George Mason University with my Masters in Earth Systems Science. Since graduate school I have been working for the Engineering Research and Development Center's Geospatial Research Laboratory. This experience, along with an insatiable curiosity, sparked my interest in returning to school to pursue my PhD. My research interest include renewable energies, terrain reasoning, the application of land atmosphere interactions to the decision making process. Outside of school and work, I am also interested in coastal ecosystems and enjoy taking any opportunity to see or travel to marine areas. In my free time, I like to be outdoors. A few of my favorite things are skiing, hiking, camping, and gardening. Email: lec170 AT psu DOT edu

Elena Sava, M.S.

I’m a Ph.D. student studying under Guido Cervone. My background is in Global and Environmental Change, which uses remote sensing and related geoinfomation technologies in detecting changes of the Earth’s systems — specifically, the interaction of the geosphere, atmosphere, ecosphere, and sociosphere within local, regional, and global scales. My interests include geographical information science (GIS), remote sensing, environmental hazards, human and physical geography, climate change, and environmental policy. My previous research involved a quantitative analysis of Chlorophyll blooming associated with the Japanese 2011 tsunami using remote sensing satellite data. Currently, my focus is on the fusion of remote sensing and social media data during emergency events such as flooding. For decades remote sensing has been used to make a substantial contribution in emergency situations and damage assessment. However, despite the immense quality of data available, geo-temporal gaps are often present due to limitation of the platform such as revisiting time, atmospheric conditions or other obstruction. The goal is to use social media data and other non-authoritative sources and fill in the gaps in remote sensing observations. Email: esava AT psu DOT edu

Carolynne Hultquist, M.S.

I am a Ph.D. student specializing in fusing remote sensing and geographic information to better understand complex environments. My research has involved machine learning techniques, the use of geospatial technologies during hazards, energy, and complexity theory. I joined the Geoinformatics and Earth Observation Laboratory to pursue research using computational methods for spatio-temporal analysis of natural disasters. I received my M.S. Geography degree at Penn State for my thesis involving validating radiation measurements around Fukushima by comparing citizen science, government data, and models over space and time. I believe it is critical to recognize the informational benefits and limitations of environmental and social data from various geospatially enabled technologies. My research interests include remote sensing, VGI, data mining, geovisual analytics, spatial cognition, emergency management, and public policy. Email: cgh138 AT psu DOT edu

Yanan Xin, M.S.

I am a PhD student in the four-year track at Penn State Department of Geography. I got my master of Urban Spatial Analytics from University of Pennsylvania. After graduation, I worked as a GIS Development Intern at DDOT. Then I found my heart was still in the academic world which prompted me to go back to campus. I am a data-driven person and I am fascinated about digging into spatio-temporal data and building numerical models. My previous research includes Local Indicators of Spatio-Temporal Association for Network Constrained Data, Rethink of Curb Parking Demand-based Pricing in San Francisco and Remote Sensing Image Fusion Method Based on Wavelet Transform. With Prof. Cervone’s guidance, I am looking forward to building my kaleidoscope to explore immense spatio-temporal data and solve problems in transportation, environmental hazards, energy and so on. My research interests include spatio-temporal data mining, data fusion, spatial statistics, social and economic networks. Email: ykx5030 AT psu DOT edu

Weiming Hu, B.S.

I am a Ph. D student in the five-year track graduate program in the department of Geography at the Pennsylvania State University. I completed my bachelor degree in the School of Remote Sensing and Information Engineering at Wuhan University. And now I’m under the advising of Dr. Guido Cervone. My main interest lies in applying remote sensing techniques to monitoring natural disasters and emergencies. Some related topics are 1) image processing and 2) social network data mining. Last year, I participated into a course on fixed-wing UAV (Unmanned Aerial Vehicle) and found that I have great a passion to learn more. Especially to learn about the multi-motor type of UAVs in order to incorporate new techniques into my future projects. Although satellites are getting higher spatial and spectral resolution and we are obtaining more data than ever with remote sensing, the real-world problems are even more complex and inter-related. Thus with the help of GIS technology, I’m able to touch and recognize the inner beauty of this world in which we live. Email: wuh20 AT psu DOT edu

Courtney Jackson, M.S.

I am a Ph.D. student working with Dr. Cervone in the Department of Geography at Penn State. I graduated from Penn State in 2015 with my undergraduate in Geography-GIS. My senior year of undergrad I worked with Dr. Cervone on testing the effectiveness and efficiency of using UAVs for emergency response to hazards. After this, I went on to pursue my M.S. in Geography at the University of North Dakota, My master's research pertained to differentiating climate and land cover change variables in a sub-basin of the Devils Lake Basin in order to determine the cause for the prolonged flooding the Devils Lake, ND area has been experiencing for the last 30 years. Now back at PSU, Dr. Cervone and I plan to continue research with using UAVs for emergency response to hazards.
