2004 Candidate Pool

- 76 applicants
- 7 (approximately) with significant computing

background. - Of these, only two applicants were from

universities comparable to, or ranked higher than

Purdue. - Pool dominated by applied math, geophysics,

theoretical physics.

2004 Candidate Pool

- Applicants with strong computational background

tended to have a broader focus than Geophysical

Fluid Dynamics or focus on other areas. - While there were a couple of outstanding (senior)

applicants, the sentiment (outside of CS

component of committee) was that they had little

background in Geophysics.

2004 Hiring Process

- Six candidates were invited for interviews
- One in computational science / home CS
- One in Theoretical Physics / home EAS
- One in Computational Geophysics / home EAS
- Three in Applied Math / home Math

Committee Recommendations

- Hiring Recommendations
- 1.0 in applied math
- 0.75 in EAS
- 0.25 in CS.

In Retrospect (hiring).

- Why was the applicant pool so small?
- The area itself?
- Misplaced advertising?
- Need for targeted recruitment?
- And even if the applicant pool were bigger..
- How likely is it that we would find an

outstanding candidate with considerable strengths

in CS and geophysics? - Is a marriage of geophysics, computational

science and applied math the best way to attract

outstanding talent in computational science?

In Retrospect (the area)

- Computational science and engineering is an

extremely well-funded area at Purdue, as well

as nationally. - There is considerable demand for expertise in

this area across campus. - Is it desirable to strengthen this group,

especially, in view of Purdue's historic strength

and attrition over the years? If so, how do we do

this in the context of COALESCE?

COALESCE Nanosciences

- Core research themes in this area include

theoretical, experimental, and computational

aspects of low dimensional quantum systems,

molecular electronics, and molecular scale

biophysics and biochemistry.

COALESCE Nanosciences

- This is an important thrust area, nationally, and

is an area of strategic growth within Purdue. - The area is supported by a large grant from NASA

on experimental activities and one from NSF on

computational activities (both of these projects

are led out of ECE). CS has participation in the

NSF project. - Birck Nanotechnology Center and Bindley

Bioscience Center provide necessary experimental

infrastructure.

2004 Candidate Pool

- 175 applicants
- 4 (approximately) with significant computing

background (two of these overlap with CSE). - Pool dominated by physicists and chemists.

Search Committee

- Committee Chair Giordano (Physics)
- CS represented by Ahmed Sameh

2004 Hiring Process

- Thirteen candidates were invited for interviews
- One in computational nanoscience / home CS (same

as the computational science candidate) - One other invitee was somewhat computational in

his approach. - Most of the other candidates would have Physics

as their primary home.

In Retrospect (hiring).

- This is an area of considerable emerging

importance. Why was the applicant pool so small? - Perhaps, hiring in computational nanosciences is

premature? - Perhaps, we werent looking in the right places?
- Perhaps, we need to broaden our perspective of

what computational nanosciences is? - Due to its relative youth, some resistance was

observed in committee towards hiring

computational nanoscientists. What is the best

way to address this?

In Retrospect (the area)

- There have been fruitful collaborations between

CS and ECE in areas of modeling nano-scale

phenomena. - There are emerging collaborations between CS and

material scientists in multiscale simulations of

such phenomena as crack propagation, laser

ablation, corrosion. - Such collaborations are less forthcoming with

other departments in science at Purdue. How do we

address this?
