Department Chair

Paglione, Timothy
Full Professor
O: AC-2F09B
Prof. Paglione's main field is microwave spectroscopy of interstellar molecular clouds. He studies primarily the very largest clouds in galaxies, which form the most massive stars. These stars live furiously, greatly affecting their surroundings with their winds and radiation, then die dramatically in giant explosions that enrich the interstellar medium in heavy elements. Their lives are relatively brief as well ("only" 10 million years or less) so their impact is not only profound but immediate. Certain galaxies known as starbursts create numerous clusters of these massive stars in their centers. Dr. Paglione studies the gas that forms these stars in starbursts and in our own, normal, Milky Way Galaxy, estimating their physical properties and comparing them with the galaxy dynamics. Dr. Paglione also studies the gamma-ray emission from starburst galaxies and the Milky Way, which originates from supernovae and their particle reactions and other high energy emission mechanisms.

Borenstein, Samuel
O: AC-2F09A
Since June of 1994, I have been involved in a NASA/AMP (Alliance for Minority Participation) grant to bring students from the high schools and colleges of New York City into a mainstream research environment, as well as to afford the faculty members involved an opportunity to embark in a new field of research. This has been an exciting and rewarding experience, in that it has allowed me to interact with earth scientists at GISS, as well as faculty members and students in the local urban environment. I have participated in the PINATUBO group of the Institute on Climates and Planets ICP where the nature of the research is to evaluate the relative success or skill of the GISS General Circulation Model of the atmosphere GCM, by comparing its prediction with ground based and remotely sensed observations of climate parameters such as temperature, precipitation, wind velocities, geopotential heights etc.

Assistant Professor

Predictions of metal(loid) transport processes in natural system are a critical aspect of decision-making in risk assessment, and remediation strategies. I aim to advance our understanding of how physical, chemical and biological factors interact and control the mobilization of trace metals in natural environment. My research is focused on the local hydrological and geochemical controls in mobilization of heavy metals and nutrients in natural waters. Specifically, I investigate the potential role of microbes and dissolved organic matter (DOM) in mobilization of trace metals in groundwater of contaminated area. Field sampling program and laboratory measurements are combined to study behaviors of these elements in both sea and fresh water environment.

Khandaker, Nazrul
Associate Professor
O: AC-2E15

Khandaker has field and research experience in environmental geology, sedimentology,and tunnel geology. Khandaker utilizes numerous independent lines of evidence, including field and geochemical studies to characterize and interpret a variety of geological systems.  Khandaker worked as a geotechnical consultant (2001-2008) for the Water Tunnel #3: the largest capital construction project in NYC; accomplished soil and rock core characterization; petrographic,geochemical investigations, surface & tunnel mapping, and geotechnical reports, based on ASTM Standards. Khandaker is a Certified Professional Geologist (State of Wyoming).

Lynch, Kevin
Assistant Professor
O: AC-2F09
My main field of research is precision muon physics. I have been involved in high precision measurements of the free muon lifetime (MuLan), as well as the capture rate of negative muons on protons (MuCap) and deuterons (MuSun). My current research projects include two precision measurements at the Fermi Accelerator Laboratory outside Chicago: a precision measurement of the muon's anomalous magnetic moment (muon g-2) and a search for muon to electron conversion (Mu2e). My areas of technical expertise include simulation, distributed computing for data acquisition, data acquisition electronics and systems, and data analysis on large physics data sets. I have dabbled in particle physics detector development and vacuum system design, and hope to expand my work in these areas in the future.

Popp, James
Assistant Professor
O: AC-2F09C
I am an experimental particle physicist interested in developing techniques and equipment to probe new physics beyond the Standard Model of Elementary Particle Physics. I am deeply involved in the Mu2e Experiment at Fermi National Accelerator Laboratory in Batavia, IL. This project is meant to test some of the most strongly-held conservation laws of nature: conservation of electron, muon, and overall lepton number in particle interactions. At the same time, I have a strong interest in finding practical applications for particle detector technologies. I have recently become involved with health and environmental physics research. Teaching physics at the graduate and undergraduate level is of particular importance, both in broadening and deepening my investigations, and mentoring future scientists.

Schleifer, Stanley
O: AC-2F09D
Before becoming chairman of the Dept. of Earth & Physical Sciences, I had been a professional geoscientist for over 40 years. My specialties are in field geology, environmental geology, engineering geology, structural geology and geophysics. Throughout my years at York College, I have 'kept one foot in the working world and one in academia'. Whenever possible, I have let my students become involved in, or at least observe the work I was doing.

Wolosin, Dora
Assistant Professor
O: AC1E14

The focus of my research at York College, carried out in collaboration with the FDA, is the development of highly sensitive methods for the identification of pathogens in environmental samples Bacteria present in the environment are a source of many food-borne disease outbreaks. Detection of pathogen contamination in our food and water supply, as a result of natural events or terrorist actions, is essential to minimize morbidity and deaths. In addition, the agricultural industry benefits from improvements in the control of food processing.

My present studies seek to establish rapid real time quantitative PCR-based tests for the simultaneous determination of multiple pathogenic bacteria. Using pure preparations of bacterial DNA as templates, the first step, under progress, is the development of an extended family of primers consisting of sensitivity-matched dual primers sets for each bacterium.
