Selected work · 01

Stridor

One instructor console drives patient cases, a ventilator waveform trainer, lecture decks and live polls that students answer on their own phones. A physiology engine moves the monitor as orders are given, and every answer feeds reports by NBRC content area and course outcome.

Ventilator. Eight modes, live waveforms and loops.
ECG. Dual-lead strips on calibrated paper.
Reports. Results by NBRC content area.
Lectures. Slide decks with live polls on students' phones.

Oxygen Journey

Follow a breath from the air to the cell, in 3D.

Airways. Bronchial tree to the alveolar sacs.
Gas exchange. Across the alveolar-capillary membrane.
Delivery. From the aorta to the capillary bed.
Internal respiration. Oxygen unloads to the mitochondria.

Selected work · 02

Respiratory Lab

Interactive oxygen, humidity and aerosol modules.

Students change the device, the flow or the particle size and see the result: aerosol travelling to the lungs, where particles deposit, how bland aerosol reaches a trach collar, how a Venturi mask entrains room air, and how the oxyhemoglobin curve shifts.

Aerosol delivery, the complete path. A 3D airway with labeled branches and adjustable breathing rate.

Particle deposition. Change particle size and breathing pattern; watch where particles land.
Bland aerosol delivery. Droplets from the nebulizer through the tubing and water trap to the trach collar.
Venturi mask. Pick the FiO₂ adapter; watch room air entrain against demand.
Oxyhemoglobin curve. Choose lung, resting or active tissue and shift the curve.

StridorEHR

A simulated electronic health record.

Built for chart-based learning: 43 patient records across ICU, step-down, sleep lab and outpatient settings, each with chart review, results, imaging and ECG, notes, medication administration, orders and RT flowsheets. Students work from the chart; the answer key is kept in a separate faculty build.

Inside the chart
Imaging and ECG. Radiology, rhythm strips and hemodynamics.
Results review. Trended labs with ranges and flags.
Medication MAR. Time-based administration by order.
RT flowsheets. Device, settings, vitals and assessment.

Beyond the Grade

Question-level assessment reports.

An assessment system that turns exam results into a Student Learning Report for every student, a faculty cohort analysis, and structured reflection and development plans. Every question is tagged by content area, cognitive level and NBRC domain, so each student can see where they stand and what to study next.

How the reports work
Student Learning Report. Results, strengths and a priority learning plan.
Performance by category. Content group, cognitive level, NBRC domain.
Faculty cohort analysis. Score distribution and results by content group.
Reflection and development. Students' written reflections and action plans.

Sample reports generated from fictional test students.

About Me

Teaching approach

  • Constructivism
  • Experiential learning
  • Scaffolding
  • Humanistic

I am a respiratory care educator, registered respiratory therapist, and licensed professional counselor with a professional background spanning clinical practice, healthcare education, and student development. I currently serve as tenure-track faculty in the Respiratory Care Program at Malcolm X College, where I also began my own respiratory care education. Returning to the institution that helped shape my professional journey has given me the opportunity to contribute to the development of the next generation of respiratory care practitioners.

My educational background includes a Master of Science in Rehabilitation Counseling, along with professional credentials in respiratory care and neonatal/pediatric respiratory specialty practice. My experience in clinical respiratory care, professional training, and competency development informs how I approach teaching. I recognize that preparing students for clinical practice requires more than delivering technical information. It requires helping them develop clinical judgment, professional accountability, adaptability, and the confidence to make safe, evidence-based decisions.

My teaching philosophy draws on constructivism, experiential learning, and Vygotsky's principles of scaffolding. I believe students learn most effectively when they actively engage with information, connect theory to practice, collaborate with others, and receive purposeful feedback. In my classroom, laboratory, and clinical instruction, I incorporate patient-centered case studies, simulation, hands-on demonstrations, structured clinical reasoning exercises, and competency-based assessments.

I have a particular interest in instructional design, educational technology, and the meaningful use of assessment data. I develop interactive learning resources, browser-based clinical simulations, and digital educational tools that create opportunities for students to apply their knowledge in realistic clinical situations. My Beyond the Grade initiative reflects my commitment to using assessment evidence to identify learning gaps, refine instruction, and help students take a more active role in understanding their academic progress.

My background in counseling also shapes my approach to education. I value the relationship between student well-being, motivation, self-efficacy, and academic success. I strive to create an environment in which students are supported, challenged, and held to meaningful professional standards. Beyond the classroom, I contribute to institutional initiatives involving faculty onboarding, wellness, and professional development.

Ultimately, my goal as an educator is to prepare respiratory care practitioners who can do more than perform procedures or recall information. I want students to understand the reasoning behind their decisions, recognize when their approach needs to change, and enter clinical practice equipped to provide safe, thoughtful, and compassionate patient care.
