Responsibilities and Interests

Management and Administration

I direct and manage the operations of a multi-function, multi-user Soil Research Cluster Laboratory (SRCL) in the Department of Ecosystem Science and Management (ESM), College of Agricultural Sciences at The Pennsylvania State University.  The SRCL is an educationally-based multi-function, multi-user analytical laboratory in the College of Agricultural Sciences and provides students, faculty and staff access to instrumentation and equipment that may not be available in individual laboratories and that find common use by several research groups. Unlike many laboratories that run routine methods of analysis, the SRCL provides the opportunity for faculty, research fellows, postdocs, laboratory technician and technologists, and graduate and undergraduate students to be guided in developing and testing novel methods suited to their research efforts. The SRCL analytical instruments and research methods and procedures are not limited to soil; they also have been employed in the analysis of plant and animal extracts and digests; water and waste water; biosolids; and geologic and synthetic materials. The main objectives of the SRCL include:

•    Providing centrally accessible instrumentation and equipment for chemical analyses of soils, water mixtures, biosolids, biological and detrital samples, and geologic materials in support of research.

•    Providing centrally accessible instrumentation and equipment for soil physical, pedological, and hydropedological analyses in support of research.

•    Building, preserving and upgrading the knowledge and skills required for the optimal operation and research capability of the SRCL by developing analytical procedures suited to individual research needs.

•    Teaching faculty, staff and student researchers to apply analytical instrumentation, knowledge and skills most fruitfully.

•    Supporting teaching activities and encouraging classes to use current analytical equipment in the SRCL to obtain hands-on experience in soil, plant, water, and environmental analyses as well as in quality assurance and control procedures.

•    Ensuring that efficient means exist for students, staff and faculty to produce timely, accurate, and validated analytical results.

Teaching

SOILS 597D - Ecosystem Analytical Techniques

SOILS 597D is a three-credit advanced quantitative laboratory experimentation course that is designed to give you a deeper understanding of modern analytical instruments and the background theory and principles underlying ecosystem chemical measurements. Upon completion of the course, you will be well versed in, and able to apply appropriate techniques used to measure the chemical condition of ecosystems such as atmospheric, soil and geologic, aquatic, plant, animal, and insect chemical constituents. Instrumental methods of analysis will include: spectroscopic, chromatographic, spectrometric, electrochemical, and thermal methods for ecosystem measurements.

SOILS 597E: Ecosystem Laboratory Quality Control

The course gives an overview of the necessary actions to be taken to make sure that ecosystem analytical data of known quality objectives are obtained. The data quality objectives covered in the course include accuracy, bias, trueness, recovery, precision, sensitivity, instrument and method detection limits, decision limits, calibration lower range limits, homogeneity of variance and linearity tests, selectivity, specificity, measurability, reliability, validity, timeliness and control charts. Implementing a quality control program is one of the requirements to be in compliance with the U.S. Environmental Protection Agency’s Good Laboratory Practice

AG 160S - Introduction to Ethics and Issues in Agriculture

AG 160S is a three-credit course that introduces students to contemporary issues, ethical theories and principles, and the application of critical thinking and communication skills related to topics in agriculture, renewable natural resources, and the environment.

 

Research Interests

  • Development of instrumental methods of analysis applicable to soil chemistry, soil fertility, soil physics, pedology, and hydropedology.
  • Development of measuring and analysis technology.
  • Development and implementation of quality assurance and quality control procedures in soil analytical laboratories.
