Areas of Interest
- Large-scale, field operations including
atmospheric dispersion studies, environmental
remediation technology demonstrations and
- Tracer technologies including indoor and outdoor
dispersion/transport studies. Designing low-power,
high-quantity, equipment for remote locations (e.g.,
battery-powered low flow dispersion systems,
rack-mounted release and sampling systems for use in
the upper troposphere to lower stratosphere).
- Environmental investigation of hazardous
material transport including air and water
transport, in-situ treatment technologies for
hazardous and radioactive contamination,
verification and monitoring technologies for
subsurface barriers and cap/cover systems and
development of advanced engineering solutions for
containment, solidification and stabilization of
- Head of BNL Meteorological Services, which operates
and maintains the BNL meteorological network. This group
provides data to the site and researchers. The data is
used for emergency operations, in transport modeling for
dose assessment, in local climatological research, etc.
The group maintains a 100 meter tower, a 10 meter tower,
the data acquisition building and database (both current
- Meteorological monitoring at the 32MW solar farm
located in Upton, NY. The Meteorological Services group
installed and maintains solar irradiance and
meteorological sensors within the farm. The sensors
include 64 SP-Lite2s distributed at 25 locations (near
inverter boxes) as well as air temperature, panel
temperature, relative humidity and soil temperatures
(under array and walkway). In addition, we maintain a
solar irradiance base station that includes a
pyrheliometer (CHP-1), a pyrgeometer (CGR-4), shaded and
unshaded research grade pyranometers (CMP-22), one
reference solar panal (identical to the solar farm
panels) and reference SP-Lite2s mounted horizontal and
in-plane (matching the solar farm). The group also
collects and maintains the database for these sensors.
- Principle Investigator for Lidar development effort
in support of Office of Naval Research Program for the
Encapsulated Perfluorocarbon Tracer Tag, Track and
Location System. BNL is developing a mini-LIDAR for the
effective stand-off detection of an enhanced duration
Perfluorocarbon tracer (PFT) taggant. Based on a CO2
infrared laser, the goal of this project is the
stand-off detection of a PFT, in air, at levels of
0.01ppb-m at 0.5 km.
- Principle Investigator for “Perfluorocarbon Tracer
Support for AFTAC Atmospheric Studies”. In this program,
BNL was tasked to give technical assistance in designing
a 500 to 1000 km atmospheric tracer dispersion study and
to design, build and test a complimentary tracer release
system that was low power, compact and could be used in
- Principle Investigator for “Tracer Studies – Urban
Dispersion Program”. The objective of the New York City
Urban Dispersion Program (UDP) [2004-2007] was to study
air flow in an urban environment, which would allow
validation of transport models. This was the largest
urban atmospheric transport study completed to date.
Data collected during these studies are being used to
improve and validate computer models that simulate the
atmospheric movement of contaminants within cities, and
around, into and within building interiors. The first of
the field studies occurred in March, 2005 and a second,
larger field study was completed in August 2005. This
second study also contained a subway dispersion test.
- Principle Investigator for “Using Mini-LIDAR for
Verification and Long-term Monitoring of Cover Systems”.
This project developed a LIDAR system that can be used
for standoff detection of PFTs in the air.
- Principle Investigator for “Development of
Perfluorocarbon Tracer Technology for Verification of
Cover Performance”. This program successfully performed
proof-of-concept testing of a cover verification
technology that uses of gaseous perfluorocarbon tracers
to measure cover performance. As a secondary objective,
we also demonstrated a field-deployable PFT detection
- Principal Investigator for
"Stabilization/Containment Systems". The primary
objective of this project was to develop and demonstrate
at a field-scale, emplacement of a close-coupled barrier
technology capable of containing waste forms within
their existing subsurface disposal or storage
structures. Engineering developments included dual-fluid
jet grouting to allow the use of acrylic polymer grouts.
The PFT technology was successfully deployed at a test
site and at two subsurface barrier demonstrations.
- Provided technical assistance to DOE In Situ
Stabilization projects in determining which grouts will
be viable candidates for in situ stabilization.
- Joint research project with the Russian Research
Center, "Kurchatov Institute" in Moscow, Russia, to gain
a better understanding of the performance of waste
packages in the Kara Sea.
