Instrumentation: I am interested in the design and construction
of instruments related to remote sensing such as radio telescopes, radars,
sensor networks and biological sensors. I am interested
in frequency bands from VLF to optical, and in most of the devices related
to the remote sensor such as antennas (arrays and interferometry),
antenna-receiver coupling systems, high power transmitters and amplifiers,
low-noise amplifiers, mixers, oscillators, digital correlators, calibration
systems, and cryogenic systems.
Experience in this area:
In my research as a Ph.D.
student I have worked on radars and passive receiver technologies with application
to ionospheric studies. I have participated in work related to VHF
Incoherent Scatter (IS) Radars (such as AMISR, Millstone Hill at MIT
Haystack observatory) and UHF IS radars (such as EISCAT Tromso and
Sondrestrom). I have been also exposed to the construction of detectors in
LF and VLF bands to detect low frequency ionospheric radiation. As part of my research
I have also collaborated with the design and construction of a new auroral imager
that uses high speed ccd cameras.
As a researcher in the
Deuterium array project at MIT Haystack observatory, I worked on the
construction of a Radio Telescope. I collaborated actively with the radio
interference mitigation system, the calibration system, the digital
receiver and correlator, and with the antenna array modeling
(electronically steerable). I also
collaborated with other projects developed at Haystack such as the Small
Radio Telescope project.
In my collaboration with
Receiver Lab at Smithsonian Astrophysical Observatory I have worked with
far infrared technology. I collaborated in testing and operation of mixers
and local oscillators to different sub-mm bands. I have also collaborated
with the Fourier Transform Spectrometer and the Receiver Lab Telescope
operated in San Pedro de Atacama, Chile.
Modeling: I am interested in
the use of computational methods, such as numerical solution of
stochastic partial differential equations and simulation, to study complex physical systems.
The systems of my interest are: Interaction between electromagnetic waves and materials,
semiconductor devices, electronic circuits, antenna synthesis, antennas array as well as
ionospheric and atmospheric dynamics.
Experience in this area:
In my research as a Ph.D.
student I have worked with a particle simulation to study the effect of
plasma instabilities on Incoherent Scatter Radars. I have gained experience
in parallel computing through this investigation. I have also worked on a
numerical model of AMISR, a new electronically steerable radar.
In my collaboration with the
Receiver Lab at Smithsonian Astrophysical Observatory I worked to develop
an atmospheric water vapor model developed using the data collected with
the Fourier Transform Spectrometer settled in Chile.
