Xiaozhi Bai
1. IST on call expert for Run15
2. Develop EvtGen into STAR official simulation

Jonathan Bouchet
1) SSD soft coordinator (AGML geometry modeling, FastSimMaker,
embeddingMaker, revamping code to SST, contact person DB table,
revamping DB tables for SST)
2) initial AgML PXL , PST geometry
3) revamping code for alignment (StHftPool) ; several simulations for
misaligned/tilted PXL ladders/sectors for dev13/dev14 geometries

5) KFVertex in pp (with TMVA)
6) comparison KFParticle/TCFIT
7) StFMSPointMaker, StFgtSlowSimuMaker reviews
8) HLT-HFT standalone

Liang He
1. I did the first detailed simulation of HFT performance in pp collisions and also figured out the way to correct the bias of primary vertex reconstruction due to displaced tracks from D mesons. These benefit many heavy flavor analyses
2. I studied the impact of D^0 meson reconstruction in pheriphral Au+Au collisions using KF reconstruction and found the KF method significantly improved the D^0 meson significance in prepherial collisions. These impact are important for Rcp measurements and  also benefit many other D meson analyses.

Leszek Kosarzewski:
Slow Simulator for IST.
Talk at a Junior`s day, which may be useful for newcomers. Jerome asked me to put it on the tutorials webpage:
- https://drupal.star.bnl.gov/STAR/comp/sofi/tutorials/introduction-star-software-and-makers
- https://drupal.star.bnl.gov/STAR/system/files/STAR_soft_BNL_LK_2015_6_1.pdf

Michael Lomnitz:
- I was in charge of PXL masking and contributed to other software and calibration tasks for HFT.
- Developed my own alignment code and contributed to HFT internal alignment and cross checks
- Supported Hao with Sti tracking efficiency studies at the beginning of the year.
- Studies of KF particle package and D0 reconstruction in simulations
- Ongoing contributions to the RNC-HF analysis library (presented by Jochen during the junior day in this last collaboration meeting): Built classes for pair, triplet and quadruplet reconstruction, etc.
- Developed Toy MC package together with Mustafa Mustafa.
- Incorporating MC information into PicoDst maker.
- Set up simulation template for HF decays in Hijing background and supported other students/posdocs in the their own studies.
- EPD R&D work: procured material, designed and built tiles and setting up test bench.
- Assisted in installing pEPD in IR and provided online/offline QA for this test.

Rongrong Ma:
1. I have been serving as the MTD soft coordinator since March 2014, and being the contact person for any software-related issues for the MTD group.
2. I developed, implemented, tested the two-iteration production chain for the Run14 MTD data production.
3. In 2014, I also developed the MTD algorithm in HLT, and I will continue working on this later this year.
4. I took one month of MTD on-call shift this year.

Long Ma:
For the service work, I was involved in HFT pixel detector calibration work on alignment and efficiency studies during Run13 and Run14.

Mustafa Mustafa:

Hao Qiu:
I conducted PXL sectors survey. The running of survey for ~20 sectors took more than 2 months. Even more time was devoted to the development of the survey procedure.
I wrote PXL hit reconstruction makers, including StPxlRawHitMaker, StPxlClusterMaker, StPxlHitMaker and related DB tables, and made sure they run well in STAR BFC.
I improved Sti tracking with HFT, proposing more than 10 modifications which greatly increase HFT tracking efficiency.
I served as the software coordinator for the PXL detector.

I serve as a GPC member of the low pT Jpsi paper.

I set up the main frame for the STAR High Level Trigger (HLT) system. I did the major part of the work for coding the new system including the refinement of tracking software inherited from the previous STAR L3 system, and I added TPC hit transformations and distortion correction maps, BEMC data processing, primary vertex reconstruction, beam line real time calibration and preliminary tracking for the HFT in HLT. I also played an important role in maintaining the HLT during the 2009 -2011 data taking runs.

I initiated the simulation for the STAR inner TPC upgrade.

I was responsible for several items of STAR TPC calibration activities, including space charge and grid leak corrections for Run 8 and Run 9 pp 200 GeV collisions and Run 10 200 GeV AuAu Collisions. I also did t0 calibrations for Run 8 pp 200 GeV collisions, and sector alignment for Run 7, Run 8 and Run 10. I was responsible for creating a new method to use charged particle tracks for TPC sector alignment.
