RESEARCH EXPERIENCE
May 2005 - Present: Spitzer Science Center (SSC), Caltech, Pasadena, CA
• Coronagraphic Observations of Debris Disks: to expand the sample of resolved debris
disks in scattered light.
• Gas evolution in protoplanetary disks: to understand the transition from optically thick to
optically thin protoplanetary disks.
• High temperature plasmas in young stars: to understand accretion columns in Classical T
Tauri Stars.
• Debris disks around stars with planets: to study the relationship between debris disks and
stars with planets.
August 2002 – May 2005: Advanced Camera for Surveys, Johns Hopkins University,
Baltimore, MD
David R. Ardila, CV Nov. 2007 1

Associate Research Scientist with the Guaranteed Time of Observation (GTO) Science Team
of the Advanced Camera for Surveys (ACS). As part of the circumstellar disk group,
designed, reduced, and analized observations of circumstellar disks around main-sequence
stars. Performed dynamical and radiative modeling of optically thin scattered-light optical
images of disks.
August 1997 – September 2002: University of California, Astronomy Department,
Berkeley, CA
As a graduate student performed research in a variety of fields.
• In star formation, studied the interaction between the disk and the central star in
Classical T-Tauri Stars, using high resolution optical (the Hamilton echelle spectrograph
on Lick Observatory and HIRES on Keck) and UV (GHRS and STIS on HST)
spectroscopy. Also, studied the origin of brown dwarfs, by searching for circumstellar
disks around these objects, using mid-IR photometry (primarily ISAAC at VLT and
NIRC at Keck).
• In the search and characterization of low-mass stars and brown dwarfs, lead survey
searches for these objects in young clusters, using wide field cameras (the Michigan
Curtis-Schmidt at CTIO, and the Prime Focus Camera at Lick Observatory) and lowresolution
spectroscopy (LRIS at Keck, and the Kast Spectrograph at Lick).
• Other studies included the characterization of chromospheric activity in low-mass stars
(using low-resolution spectroscopy) and nature of the X-ray emission in Classical T
Tauri Stars (using Chandra).
August 1993 - December 1994: Purdue University, Physics Department, West Lafayette,
IN
As part of the Nuclear Physics group, and under the direction of Andrew Hirsch, explored the
dielectric characteristics of Helium-Argon mixtures to be used as media for the Solenoidal
Tracker at RHIC (STAR), a detector currently in use in the Relativistic Heavy Ion Collider at
Brookhaven National Laboratory.
1992: University of Los Andes, Physics Department, Bogotá, Colombia.
As part of the condensed matter group, performed theoretical investigations in the quantum
Hall effect, as occurs in 2-D electronic systems.
INSTRUMENT EXPERIENCE
May 2005 – Present : Spitzer Science Center, Pasadena, CA
Functional work at SSC divided among the Infrared Spectrograph Group (IRS) and Observer
Support. In addition, lead the effort for the Spitzer Spectroscopic Heritage Atlas.
For the IRS, duties include:
• Periodic spectrophotometric calibration of the spectrograph and peak-up arrays.
• Design of observations campaigns to obtain standard star observations
• General monitoring of the precision and accuracy reachable with the IRS
• Managing and updating webpages relating the spectrogrph (calibration information,
known artifacts, etc)
For Observer Support, the duties include:
David R. Ardila, CV Nov. 2007 2

• Performing technical reviews of accepted proposals
• Updating of the IRS manual and Data Handbook
• Monitoring bright object limits
• Answering community questions on the spectrograph
As lead of the Spitzer Spectroscopic Heritage Atlas:
• Select targets for the Atlas, design AORs for observations.
• Interact with team members regarding scientific priorities for the Atlas content.
• Reduce current archive data, design final archive.
As an SSC member:
• Participate and contribute to talks regarding final form of the Spitzer Data Archive.
June 1999 – August 2002: Space Sciences Laboratory, Berkeley, CA
Responsibilities included writing software for the Reuven Ramati High Energy Solar
Spectroscopic Imager satellite (RHESSI), launched in 2002. The software produced simulated
data for the purposes of testing all the aspects of the spacecraft's data collection systems,
extracted telemetry information from the spacecraft data streams, and processed and analyzed
the scientific data from the satellite. Responsible for designing robust, reliable, and clear
software used by the satellite's end user.
1995: Lawrence Berkeley National Laboratory, Berkeley, CA
As part of the STAR development team, designed and developed testing procedures for
detector parts. Wrote software to control machinery that measured different characteristics of
the device (such as electrical and physical integrity, mechanical soundness).
